Meghan Markle is close to her "free-spirited" mother and her "thoughtful, inspiring" father, with the actress having written lovingly of her relationship with both.
But it is the American star's extended family that has hit the headlines, with one newspaper describing it as a "motley collection of individuals who, between them, have a long record of boozing, bust-ups and bankruptcies".
The mother: 'Free spirit' with dreadlocks and nose ring is daughter's pride
Doria Ragland, 60, was born in Los Angeles to an antique dealer father and a mother who was a nurse.
She attended the Fairfax High School, where she was remembered as bright and friendly - the teenager with the "Afro" hairstyle who loved listening to Marvin Gaye and dining out at a local Mexican taco joint with friends.
After school she worked as a make-up artist, which is how she met her husband, Thomas Markle, a lighting director in Hollywood. The pair married in 1979 and Ms Markle was born two years later.
The family moved into a house in The Valley, LA, to a neighbourhood that Ms Markle described as "leafy and affordable".
Ms Ragland and Mr Markle divorced in 1987, but remained friends.
Ms Ragland took a job as an air stewardess, meaning their daughter was frequently cared for by her father.
She later returned to university to obtain a masters in social work, following on from her BA in psychology.
She now lives in the house she inherited from her father in 2011 in the Crenshaw area of LA.
Ms Ragland and her daughter are extremely close - Ms Ragland once drove a car with the number plate MEGNME - and Ms Markle has spoken of her pride in her free-spirited mother, with her dreadlocks and nose ring.
The father: 'Hard-working' award-winning lighting director
Born in Pennsylvania, of Dutch-Irish descent, Thomas Markle, 72, made his way to Hollywood where he worked as a lighting director.
He worked for many years on the set of the television show Married With Children, and his work on long-running series General Hospital earned him nine Daytime Emmy nominations, of which he was twice named the winner.
He was also reportedly chosen to oversee the lighting for the 1984 Los Angeles Olympics as well as the 1986 Oscar ceremony.
Prior to meeting Doria Ragland, he had been married to Roslyn, with whom he had two children - Samantha, now 52, and Thomas Jr, now 50.
Mr Markle and his daughter were very close, with the young Meghan accompanying him on film sets and being cared for by him while her mother was travelling as an air stewardess.
He has not met Prince Harry, but has spoken to him on the phone and has given his blessing to the Prince asking for his daughter's hand in marriage.
Since retiring, Mr Markle moved to Mexico. He was declared bankrupt in June 2016.
Miss Markle has described her father as the "most hardworking father you can imagine".
The siblings: Growing up like The Dukes of Hazzard
Thomas Markle Jr, a 50-year-old window fitter, lives in Grant’s Pass, Oregon.
He said his family was “like The Dukes of Hazzard and The Simpsons, versus the Royal family” – but has spoken fondly of his half-sister, with whom he grew up in Los Angeles.
He was married for 11 years to Tracy Dooley, with whom he has two sons – Thomas and Tyler.
He was arrested in January for holding a gun to girlfriend Darlene Blount’s head in a drunken argument. Mr Markle and Miss Blount are now engaged.
Half-sister Samantha Grant, 52, lives in Florida and is a wheelchair user and suffers from multiple sclerosis.
She caused a stir in April when she announced she was writing a book entitled The Diary of Princess Pushy’s Sister.
Despite not having spoken to her in nine years, Ms Grant lashed out at Ms Markle in numerous interviews. She since says she was misquoted.
The ex-husband: First wedding was on a beach in Jamaica
New York-born film and television producer Trevor Engelson, 41, was married to Ms Markle for two years, until 2013.
The pair married on the beach in Jamaica in 2011, tying the knot at the Jamaica Inn in Ocho Rios, in front of around 100 guests.
They are believed to have been dating for seven years before they married.
Their August 2013 divorce cited irreconcilable differences, and their work schedules - he is based in Los Angeles, while she began filming legal drama Suits in Toronto the year they married.
He is working on a show about a man whose wife runs off with a prince.
