Meghan Markle's half-sister Samantha has called on the princess to let her and dad Thomas Markle meet Archie and newborn Lilibet.
In an interview with Inside Edition following Meghan's infamous Oprah appearance, Samantha said the real truth was "totally ignored and omitted".
Samantha added: "Depression is not an excuse for treating people like dishrags and disposing of them."
Meghan's half-sister, 56, has sided with Thomas Markle during his five-year battle with the daughter of his second wife.
She was not invited to Meghan's fairy-tale wedding to Prince Harry and was further upset when Meghan described herself as on "only child" during the Oprah appearance.
Meghan also said: "[Samantha] changed her last name back to Markle in her early 50s … only when I started dating Harry.
"I think that says enough.”
Thomas Markle welcome Samantha and son Thomas Jr during his first marriage with Roslyn Loveless, with the pair separating in 1973.
He married Meghan's mum and ex-yoga instructor Doria Ragland in 1979, with Ragland giving birth to Meghan two years later.
Doria divorced Thomas in 1987.
Thomas has consistently spoken out against Meghan's conduct in the years of their estrangement, most notably selling a private handwritten letter she sent him to the Mail on Sunday.
The newspaper lost a two-year court battle against Meghan this February over its publication of the letters and was forced to spend millions of pounds in legal fees.
Meghan did not tell Thomas about her pregnancy with Archie in autumn 2018 or about Lili in the run-up to her birth in June 2021.
The duchess has kept a cool exterior throughout the long estrangement, leaving it to Samantha and Thomas Markle to protest their isolation.
Whatever happens next, the soap opera of the Markles' family life looks set to continue - as long as certain members of the family want it to.
