Meghan Markle’s half-sister, Samantha Markle, just slammed her own mother, Roslyn.

While speaking with The Sun, the multiple sclerosis patient responded to Roslyn’s allegations her dad, Thomas Markle Sr. The former clerk from Albuquerque, New Mexico, recently advised the Duchess of Sussex to not allow Thomas back into her and Archie’s life.

“For her to judge my dad – who worked so hard and gave us such an incredible life – means she is just a jealous troll. My dad is incredible – just like Meghan said many times in her blog ‘The Tig’… All those things she said are true… My dad did a great job,” Samantha said.

Samantha credited Thomas for giving her and her siblings their value system, for teaching them to think outside the box, and for encouraging them to stand up for themselves. The author of “In the Shadow of the Duchess” said that Thomas’ grandson shouldn’t be deprived of all of these things.

“To prevent Archie from having access to him is stupid and cruel. There’s no reason my dad shouldn’t be involved in his life,” she said.

Roslyn and Thomas wed in 1964, and they were blessed with two children together, Samantha and Thomas Jr. Eleven years later, the couple divorced. Thomas, later on, wed Markle’s mom, Doria Ragland, but their marriage also ended in a divorce.

During Roslyn’s interview with Mirror, she said that Thomas was not a trusted father. She also said that he abused her, cheated on her, and took cocaine. Roslyn left her children when Samantha was just 12 years old so they both grew up under the care of their dad.

Samantha could not believe how Roslyn criticized her dad because Thomas gave her and her brother the best life that she couldn’t give them. She also denied the allegations that Thomas took cocaine and said that if he did, he wouldn’t have survived his work as a lighting director for 40 years.
