Why did Samantha Markle's first 2 children get adopted by their paternal grandparents? All related (37) Recommended  Carl Mape Jan 17 Because she was very abusive, unstable, and supposedly an alcoholic. She LOST custody of her first 2 kids to her ex-husband's parents before they were two. She has zero relationship with them, and they have zero relationship with Grandpa Thomas. She had a 3rd child and no one knows who the father is! She was very abusive, and she ran away to Samantha's mother for help. Again- this 3rd one- no relationship with Samantha, grandpa Thomas, or uncle Tomas Jr
