Here's a look at Prince Harry's future in-laws:
MOTHER: Doria Ragland
Meghan Markle has described her mother as a "free-spirited clinical therapist".
Ragland, who is African-American, met Meghan's father, Thomas Markle, on the set of the US soap General Hospital, where he worked as a lighting director when she was a temp in the studio.
"I like to think he was drawn to her sweet eyes and her Afro, plus their shared love of antiques," Markle wrote.
Ragland has worked at a day centre for adults with memory loss and as a yoga therapist.
She filed for bankruptcy in 2002.
Ragland also joined her daughter and Harry to watch the Invictus Games closing ceremony in Toronto in September.
FATHER: Thomas Wayne Markle
Thomas Markle is a former TV lighting director who worked on shows such as hit sitcom Married... with Children and popular US drama General Hospital.
He won two Emmys for his team's work on General Hospital and was nominated for countless others.
Markle is his only child from his second marriage to Doria Ragland. He has two older children from his first marriage to Roslyn Markle.
He lives a quiet life in Mexico and filed for bankruptcy in 2016 after reports he failed to pay his debts.
Markle is close to her father, who is of Dutch and Irish descent, and has described him as hardworking and caring and believing in her "grand dream" of becoming an actress.
She has paid tribute to "the blood, sweat and tears this man (who came from so little in a small town of Pennsylvania, where Christmas stockings were filled with oranges, and dinners were potatoes and spam) invested in my future so that I could grow up to have so much".
HALF SISTER: Samantha Grant
Samantha Grant - also known as Samantha Markle - describes herself as a writer, a mental health counsellor and a "blabbermouth".
She is Markle's half sister from her father's first marriage. A one-time actress and model, she was diagnosed with multiple sclerosis in 2008 and uses a wheelchair.
Based in Florida, she is 17 years older than Markle and sells jewellery to raise money to fund the feature films she writes.
Twice-divorced, she has three children - Ashleigh, Christopher and Noelle.
Like her father, she filed for bankruptcy and is estranged from her mother Roslyn - Thomas Markle's first wife - and brother Thomas Jr.
Ms Grant has been an outspoken critic of Ms Markle since news of her relationship with Harry broke, describing her in interviews as a "shallow social climber" and claiming she shunned her since making it in Hollywood.
But as rumours Harry was engaged to Markle mounted, Grant, in a television interview with Good Morning Britain, denied there was a rift between her and the actress, describing her as "absolutely lovely", "very strong", very graceful" - and also "very lively".
She insisted she was not writing a "slamming tell-all" book, but confirmed the work was called The Diary of Princess Pushy's Sister.
HALF BROTHER: Thomas Markle Junior
Thomas Markle Junior, 50, has been bankrupt once, divorced twice and faced trial on gun charges before the case was dropped.
The father-of-two lives in Grants Pass, Oregon, and works as a window fitter.
He was arrested in January 2017 for allegedly holding a gun to his girlfriend Darlene Blount's head during a drunken argument.
Charged with unlawful use of a dangerous weapon and menacing domestic violence, he faced jailed for up to five years if convicted. The charges were later dismissed. He apologised for his actions and said he was seeking help for his drinking problems.
Mr Markle Jr is not thought to be in contact with his famous half-sister but has given interviews about her and shared family photos with the media.
Thomas has two sons, Tyler and Thomas Markle III, with his ex-wife, florist Tracy Dooley, whom he divorced in 2001. His second marriage, to Iohannes Rawha, ended in 2009.
FATHER'S FIRST WIFE - Roslyn Markle
Rosyln Markle is Thomas Markle's first wife and mother to Samantha Grant and Thomas Jr.
Roslyn has said of her estranged daughter: "Everything she has said about Meghan is a lie."
The 71-year-old lives in Albuquerque, New Mexico, and has been complimentary about Markle.
"Meghan is very pretty, very nice, very polished and very classy. I never hear anything but good about her from my son Thomas (Jr)," she said.
She also has a younger son, Bobby Lucero.
