Mrs Thomas was the mother of Dean Thomas. Though she was a Muggle, her first husband was a wizard, but he never told her so, believing that not knowing the truth would keep her safe. He deserted Mrs Thomas when their son was still a small boy and was eventually murdered by Death Eaters.
When a letter arrived for Dean from Hogwarts in 1991, Mrs Thomas considered the possibility that her first husband might have been a wizard, but, like her son, was never able to confirm this suspicion.
Dean had to go into hiding in 1997 because he was unable to prove he was a half-blood to the Muggle-Born Registration Commission. Mrs Thomas and her second husband were not sure where their son had gone, and were deeply concerned, so the radio programme Potterwatch asked its listeners to contact the Thomases if they knew anything about Dean.
