Samantha Markle is Thomas Markle's eldest child from his first marriage to Roslyn Loveless. She only recently started using the surname Markle (previously, she went by Grant), in what some detractors view as a bid to ride the coattails of her sister's fame. The public's critical perception of Samantha spurred after a series of tabloid stories were published, which quoted her talking about Meghan in a pretty negative way.
For example, in 2016, on top of the Radar interview, The Sun published a piece stating that Samantha characterized Meghan as a "social climber" who has been changed by Hollywood, and had always aspired to live the life of a princess.
But after the announcement of Meghan and Harry's engagement, Samantha was singing a different tune. In a December 2017 TLC documentary, When Harry Met Meghan: A Royal Engagement (via Town & Country), Samantha bemoaned the distance from her sister, and claimed it's all a result of fabrications by the tabloids. "The truth is, I never said any such thing and there's no tape, no recording, nothing in the world that anybody could present to suggest that it was," she said, particularly of the "social climber" comment. Although in a ranging interview with The Daily Mail, published just one month earlier, Samantha did cop to confronting Meghan about her father's and her own financial problems.
As if all of this wasn't confounding enough, Samantha once again interjected herself into Meghan's relationship after Harry's admittedly clumsy remarks about the royals being the family Meghan "never had."
"She has a large family. She always did," Samantha said in a since-deleted tweet, adding, "Our dad is amazing and completely self sacrificing. We made it so that she had two houses. How fun it was!" If you're wondering how Samantha could possibly make things worse for herself, just wait, there's more.
