It's amazing how often marriages between relatives still take place these days. And many of the celebrities on this list are not some kind of perverts at all - they are outstanding and respected members of society who either entered into a relationship with a relative by chance, or fell in love at a family celebration and did not care about the rules. Either way, it's pretty weird. So, here are 14 famous people who married their relatives.

Everyone knows Kevin Bacon, because since his debut in “Menagerie” in 1978, the actor has been actively acting and has appeared in such major projects as “Apollo 13” and “Footloose.” He starred in so many films that there was even a game called “Six Steps to Kevin Bacon”, in which you had to find a connection between Bacon and any other actor in no more than 6 transitions. But Bacon had no idea that he and actress Kyra Sedgwick were connected by something more than marriage—ties of blood. The couple, who have been married for almost 30 years, are relatives in the 9th generation. This was discovered by Henry Louis Gates on the TV show Find Your Roots.

Why Marriages Between Close Relatives Are Undesirable

What is a marriage between relatives called? In the medical field, such relationships are inbred. Here we mean a family union concluded between a man and a woman who have 1 or more common relatives.

So, if in an ordinary marriage the risk of having defective children with genetic diseases is 4%, then in the case of related family unions this possibility increases 5 times.

After which he married again and again and over time he became increasingly fat and crazy. His story has been brought to the big screen several times. Perhaps none of his marriages succeeded because all his wives were his relatives - all six. In chronological order: Catherine of Aragon, relative in the 4th generation; Anne Boleyn, in the 7th generation; Jane Seymour, in the 5th generation; Anna of Cleves, in the 9th generation; Catherine Howard, in the 7th generation and Catherine Parr, in the 3rd generation.

Why Marriages Between Close Relatives Are Undesirable

The law prohibits registry office employees from officially registering relationships between siblings, parents, grandparents and children. However, marriages, for example, between first and second cousins ​​are not prohibited. The process of filing an application by future spouses and legitimizing relations in such a situation is no different from traditional actions when registering a marriage.

Franklin Delano Roosevelt was probably the most influential US president. He is the only president in the history of the country who was elected for 4 terms. He led the country out of the Great Depression with the New Deal, repealed Prohibition, and led the country through World War II. His wife Eleanor was also a prominent political figure and achieved much in the field of human rights. She was a fifth-degree relative of her husband, and President Theodore Roosevelt was her uncle.

DeMille Award for outstanding achievement in film. But the director has plenty of haters, mainly thanks to his relationship with his own stepdaughter, Soon-Yi Previn, to whom he is still married. There is a 35 year difference between the spouses.

He also married his third cousin, Martha Wales Skelton. They had six children, but most of them died in childhood, and Martha herself died at 33. Jefferson never remarried, and it was only after many years that he entered into a relationship with his own slave, Sally Hemings, who bore him at least six more children.

Azerbaijani geneticist: consanguineous marriages are dangerous for the future of the nation

Due to coronavirus outbreaks in Azerbaijan, public events are being cancelled, institutions and public places are being quarantined. Healthcare and personal hygiene are the most pressing agenda in the country today.

Elkhan Rasulov in Azerbaijan further sharpened the interest of the Azerbaijani audience in medicine. In an interview with Media.Az, Rasulov said: consanguineous or cross-cousin marriages, which are common in the republic, are the shortest way to the birth of children with incurable hereditary diseases.

“If parents are relatives, then the probability of transmitting a pathological gene to a child increases by 23-30 times compared to the average population frequency. Unfortunately, there is a high frequency of consanguineous marriages in Azerbaijan. The main part of such marriages is the second type - these are marriages between cousins. It's very dangerous and they make up the bulk of it. Approximately, up to 20% of the population are consanguineous of the second, third, fourth and distant type of relationship. Each of them is undesirable in its own way,” said the geneticist.

Rasulov listed a short list of incurable genetic diseases with which a baby conceived in a consanguineous marriage may be born. The list includes all so-called orphan (rare - EADaily ) diseases: various types of congenital cancer, hemophilia, leukemia, hereditary anemia, progeria (premature aging of the body, usually leading to the death of the patient under the age of 20), male hermaphroditism, leading to idiocy or imbecility, phenylketonuria, muscular dystrophy, pathologies of the gastrointestinal tract and excretory organs, etc.

Orphan diseases usually occur in a very small number of newborns in Azerbaijan, Rasulov explained. According to him, cases of birth of children with cystic fibrosis (cystic fibrosis) are much more common, when the respiratory system, heart, kidneys, liver and reproductive system are simultaneously affected. If a man with cystic fibrosis survives to reproductive age, he is sterile, but for a sick woman, pregnancy ends in death. The geneticist said that 7-8% of cases in Azerbaijan are hereditary thalassemia - damage to red blood cells, leading to bone marrow pathology, maxillofacial deformities, liver and spleen lesions, general immunodeficiency, and mental retardation in children. Previously, Rasulov warned Azerbaijanis that consanguineous marriages are fraught with the birth of children with Down's disease and hemophilia.

The geneticist complains that in Azerbaijan there is no public control over consanguineous marriages.

“Kazakhstan is also a Muslim country. But unlike many other such countries, before getting married, they check each other for kinship. Elders from both sides meet and determine whether there is a seven-generation relationship between the parties. Marriage is concluded only if there is no consanguinity in seven generations, so they have very few hereditary diseases,” says Rasulov.

She warned in an interview with Media that marriages between multiple consanguineous families lead to an increase in the birth of terminally ill children. Az the head of the non-governmental organization “Ümidli Gələcək” (“Reliable Future”) Kamal Ashumova .

“We work with families where children are born who need special protection, with families in which spouses are close relatives, as well as with those who got married at an early age. As long as such facts exist, educational work cannot be stopped. It is necessary to deepen activities in the regions through local executive authorities, to hold meetings with religious figures who can be directly involved in the process. If it is impossible to register an official marriage due to being a minor, religious leaders carry out the procedure for concluding a religious marriage. We must think about the country’s gene pool,” said Ashumova.

In 2021, the Milli Majlis (parliament) of Azerbaijan discussed the possibility of a legislative ban on consanguineous marriages in the country - in particular, due to the risk of having sick children. But the idea was ultimately rejected. Azerbaijani newlyweds are required to undergo a medical examination before marriage. This requirement is not always met. In addition, a very significant part of cross-cousin marriages are religious marriages concluded by a mullah in a mosque, where the main thing is not a medical certificate, but the consent of the newlyweds to be husband and wife.

“People make family ties, as a rule, in pursuit of material interests, guided by the concept: they say, let everything that I have remain for a nephew or niece, rather than for a stranger. There is more material than moral interest here - let it be our own, but we don’t need someone else’s. Parents should raise their child from childhood, explain that this is your sister, your brother. And when almost from birth they start talking about marrying their daughter off to their nephew, etc., then this is ingrained in their minds. And in the future, they believe that it is in the order of things to start a family with their cousin,” she said in an interview with Media. Az President of the Azerbaijan Republican Association of Hemophiliacs Gulnara Huseynova .

EADaily reminds that a clinical picture of genetic diseases similar to Azerbaijan is observed in Dagestan, where cross-cousin marriages are also considered the norm. The reasons why children in Dagestan are matched almost from childhood within the same family are also mainly of a material nature. In some cases - for example, in Dagestan families with aristocratic origins - closely related matchmaking is also a desire to preserve “purity of blood.” Marriages between cousins ​​for the sake of blood purity are also common in some Chechen teips.

It was Rudy Giuliani who transformed New York from a dingy, crime-ridden city into the shining, upscale metropolis it is today. Before becoming mayor of New York, Giuliani prosecuted and fought organized crime. He secured a life sentence for the famous gangster John Gotti, which led to his victory in the mayoral elections. He also took part in the presidential elections, but at some point dropped out of the race. Perhaps because of the information that was made public by the YouTube star Obama Girl, it turned out that Giuliane was married to your full sister Regina Perugia. They divorced in 1982 after 14 years of marriage.

On registering marriage between relatives

It is important to know that the legislation of the Russian Federation prohibits blood relatives from marrying. There are no circumstances that would allow this to be done, not even pregnancy.

However, when contacting the registry office, the couple is not required to report the existence of a family relationship between them. But if this fact is confirmed in the future, the marriage will be declared invalid.

Society's position

If we consider civilized peoples and countries, marriages between relatives have always been prohibited.

In Russia, cousins ​​can marry each other, since the law does not prohibit this. This right is also typical for Japan, Europe, and some US states. As for the position of society, even marriages between second cousins ​​are condemned.

If we talk about marriages between blood relatives, then in all civilized countries they are equated to a crime. Such marriages are annulled if the fact of relationship is confirmed.

Consanguineous marriages are still acceptable in Muslim countries (Tajikistan, Uzbekistan). However, this has led to the fact that the problem of hereditary diseases in these territories is quite acute.

What the law says

At the moment, consanguineous marriages are prohibited by law in many countries around the world. This is due to moral and physical considerations.

The Family Code of the Russian Federation determines that persons who are related in a descending or ascending line cannot enter into marriage:

  1. Brothers and sisters.
  2. Grandparents and grandchildren.
  3. Parents and children.
  4. Adoptive parents and adopted children.

If the adoption is cancelled, marriage between the adoptive parent and the adopted child will become possible.

Despite the above restrictions, if a couple applies to the registry office to legitimize the relationship, then they will not need to confirm or refute the relationship.

Which relatives have the right to create families from the point of view of the law?

Is it possible to enter into a related marriage? In Russia, unions are allowed only between the following relatives:

  1. Uncle and niece.
  2. Aunt and nephew.
  3. Cousins.

Greta Scacchi

This list just had to have someone incredibly sexy, and in the 80s, Greta Scacchi was a real sex symbol. The Australian of Italian descent has appeared in explicit scenes more than once during her film career, including an unforgettable episode from “Presumed Innocent” with Harrison Ford. She was so irresistible that even her cousin Carlo Mantegazza could not resist. They had a son, and not so long ago the couple got married. Their union caused a great stir both in society and in the family, which is why her career quickly faded away.

Lifting the ban

Despite this, in Rus' marriages continued to take place between those who were in the fifth, sixth and seventh degrees of relationship. And, as a rule, they were not declared invalid, since no one declared during the wedding that the bride and groom were related.

In 1810, the Synod lifted the ban on marriages based on kinship and property up to the seventh generation. Now it was possible to marry those who were related beyond the fourth degree, as well as those who were related to each other beyond the second degree.

Moreover, ancient Russian laws created obstacles for marriages between representatives of noble noble families. Thus, members of the Romanov royal family very often married their relatives, and in the aristocratic environment, marriage between cousins ​​was not at all uncommon.

According to geneticists, the dynasty of the Egyptian pharaohs died out due to the fact that marriages between siblings were practiced among them for centuries. Now in many countries, including Russia, consanguineous marriages are prohibited by law. But first and second cousins ​​can legally marry. But what do scientists say about this?

A striking historical example of the unfavorable effect of consanguineous marriages on offspring is provided by royal dynasties. Marriages of crowned heads were very often concluded for political reasons, and the choice of brides and grooms was limited to a narrow circle of reigning houses that had previously become related to each other.

The sad consequence of the chain of such related marriages was an increase in the number of hereditary anomalies, up to the birth of defective and even non-viable children.

Characteristic in this regard is the history of the House of Habsburg, where members of the royal family more than once married each other: for example, Philip II was married to a cousin in his first marriage, and a niece in his second; his son Philip III is based on his cousin, Philip IV is based on his niece. The descendants of these kings are known to be profoundly mentally retarded and incapable of any activity.

These days, consanguineous marriages are becoming more rare than they once were: in Europe and North America they do not exceed one percent; in Asia their number is higher, but even here there is a tendency towards their decrease.

Peculiar closed communities have long been formed in mountainous, inaccessible places, on remote islands. The long-term stability of the population and its small migration made consanguineous marriages here almost inevitable. Similar “isolators” have survived in some places to this day. They exist, for example, in the mountainous regions of Switzerland and in South America.

But the most surprising thing is the existence of closed religious communities in multimillion-dollar London, as well as in the USA. These include, for example, the Mennonite sect (eight thousand people), which traces its origins to a few emigrants who arrived in North America back in the 18th century. Researchers who have studied the incidence in such isolated communities with a high percentage of consanguineous marriages have consistently reported a higher incidence than usual.

Why does consanguineous marriage become dangerous for the offspring even in cases where both spouses seem to be completely healthy?

The fact is that there is a group of hereditary diseases caused by pathological changes in genes responsible for certain signs or characteristics of the body.

Moreover, the following is characteristic: one altered gene does not yet manifest itself in any way, its carrier himself remains healthy, and his child is also not at risk of a hereditary disease. But if, by chance, two carriers of similar identically altered genes become spouses, a situation arises that is dangerous for the offspring.

True, even in such a marriage the development of a hereditary disease is not necessary. And here's why: in carriers of altered genes, only half of the germ cells are marked by these changes. It is possible that it will begin to develop from two normal cells, and then the child will be born healthy, since he did not receive the altered gene from his parents.

The second option: the embryo develops from a normal cell and a cell carrying an altered gene. Then the child will also be healthy, but will become the same hidden carrier as his parents.

The marriage of two healthy people with the same hidden gene change is rare. But the likelihood of such a truly fatal meeting increases if blood relatives marry, that is, people who have one or more common ancestors, from whom both could inherit the altered gene.

This is largely why incest marriages, that is, marital unions of first-degree relatives (parents and their children, siblings), are prohibited by the legislation of most countries.

There are usually no legal prohibitions on marriages of more distant relatives, since they are less risky for offspring. However, in some countries there are restrictions for such marital unions.

There are even laws that are completely absurd from the point of view of genetics, for example, the unconditional prohibition of the marriage of a nephew with an aunt, although she may not be a blood relative, but only the wife of an uncle, or the prohibition of marriage with a stepmother, daughter or son of a spouse from another marriage, with ... mother-in-law and even his wife's grandmother. Naturally, such laws can be considered a curiosity.

The accuracy of the forecast, whether a healthy child or a sick child will be born in a consanguineous marriage, largely depends on the completeness of the information that the spouses have. The experience of medical genetic consultations shows that rural residents usually know their ancestry better, while city residents know it worse. And it’s not bad to know it out of interest in one’s own “roots”; this information becomes imperfectly necessary when the need for medical genetic consultation arises.

It has long been known that marriages between close relatives are fraught with poor heredity.

This opinion emerged based on life practice.

A large number of noble families died out in ancient times because they did not avoid incest.

Religion and science do not approve of such things at all.

Simply because there is a high risk of children being born still or with major abnormalities. People will degenerate.

That is why in our country there is a law that does not allow close relatives of the first generation to register relationships. But, the restriction does not apply to marriage between cousins. This is due to a lower likelihood of the occurrence of pathologies and their offspring.

The surname Einstein has practically become a household name, synonymous with intelligence and genius. He received the Nobel Prize in Physics and developed many significant physical theories. The majority of the world's population is not smart enough to even understand the true meaning of the formula E=MC2. Such a brilliant man, however, was rather clueless in everyday matters. They say he had a whole closet of identical suits and shoes, and he also painted the door of his house red so as not to get lost. He also married his second cousin Elsa.

Edgar Allan Poe's work has always been considered creepy, so it's not surprising that he married his cousin Virginia when he was 27. However, the fact that she was only 13 at the time is also creepy. The tragic romantic themes in Poe's violent and bloody works were most likely inspired by Virginia's difficult battle with tuberculosis and her subsequent death.

Diagnosis, prevention and treatment of hereditary diseases

If it is known that the parents of the unborn child are related, then prenatal diagnosis of hereditary diseases is carried out. Almost all gene diseases in children from consanguineous marriages are congenital and are diagnosed in newborns based on characteristic symptoms. In some cases, genetic testing is performed.

Etiological treatment of hereditary diseases associated with consanguineous marriages is impossible . Therefore, the main method of preventing genetic diseases remains screening of newborns for hereditary diseases and syndromes, genetic counseling and medical education.
