Oscar Grisham is the biological son of Gail Loman and Ryan Stocks who was adopted by Sophie Grisham when he was a few weeks old.
In September 2023, Sophie got in contact with Gail after thirteen-year-old Oscar was diagnosed with aplastic anaemia and needed a bone marrow transplant. Sophie asked Gail if she would get tested to see if she was a match and also asked about getting Oscar's father Ryan tested but Gail lied she wasn't in touch with Ryan.
