25 Famous People Who Married Their Relatives

Marrying a family member is seen as taboo. In fact, in many states across the United States, marrying family members, including cousins, is illegal. 

Yet, marrying siblings or cousins has been the norm for many cultures, including the British royal family. From iconic figures cemented in history to famous actors and actresses, you might be shocked to find out which famous figures chose to marry within their family line.

In a twist of fate, Kevin Bacon and Kyra Sedgwick tied the knot in 1988, unaware of their familial connection. Unlike many other couples on this list, the two were oblivious that they were ninth cousins removed until years later.

They appeared on Finding Your Roots in 2013, an American television series investigating your family history, where they first heard the news. Sedgwick admitted she had suspicions and asked to be on the show. So, when the big reveal happened, she had to act more surprised than she felt.

The British royal family has a long tradition of marrying relatives that extends to the present day. Prince William and Princess Catherine “Kate” (Middleton), the Prince and Princess of Wales, are closer than you think.

Prince William and Princess Kate weren't the first Prince and Princess of Wales to be related by more than marriage. King Charles' first wife, Lady Diana Spencer, and King Charles were sixteenth cousins, once removed.

Sadly, the union was not a happy one. The pair divorced in August 1996, and Diana tragically passed just a year later in a car accident.

Remember when we said the British royal family had a tradition of marrying cousins? Queen Elizabeth II and Prince Philip were related to Queen Victoria, making them third cousins

The couple married in 1947 and celebrated over 70 loving years together until Prince Philip passed in 2021. 

Jerry Lee Lewis

Knowingly, marrying family members isn't just a royal family phenomenon. In 1957, 22-year-old Jerry Lee Lewis married Myra Gale Brown, his 13-year-old cousin

This wasn't Lewis' first marriage. When he and Brown got married, he was still married to his second wife, Jane Mitcham, a fact that did not go over well with fans. This move was the nail in the coffin for Lewis' once-promising rock n roll career. 

Rudy Giuliani

Rudy Giuliani is no stranger to controversy. Several damaging allegations against him exist, one of the latest being that Giuliani married one of his family members.

In 1968, Giuliani married his second cousin, Regina Peruggi. The two were married for 14 years until Rudy annulled the marriage in 1983 before he became the United States attorney for the Southern District of New York.

King George VI married Elizabeth Bowes-Lyon, his thirteenth cousin, in 1923. Lady Elizabeth rejected his proposal twice in 1921 and 1922, as she wasn’t ready to make the sacrifices needed to join the Royal Family.

King Henry VII married his cousin Elizabeth of York in 1486 when she was twenty-years-old. Their age difference and close relationship were considered standard at the time and even beneficial, as their marriage united the Houses of Lancaster and York.

When he was 27, Edgar Allan Poe married his first cousin, Virginia Eliza Poe. Edgar’s first cousin Virginia was just 13-years-old when the two tied the knot.

Biographers have long speculated that Edgar and Virginia’s relationship was more like that of two siblings as she referred to him as “Eddy,” and he called her “Sissy.” Sadly, Virginia passed in 1847 from tuberculosis. While it’s unknown whether the two were more like siblings than lovers, Poe wrote several poems dedicated to his young love after her sudden death.
