Tomas (The Triple Knife)
From Tardis Wiki, the free Doctor Who reference
Tomas was a man who lived in France during the 14th century. At some point during his life, he met and married Ashildr.
Using the alias Alys, Ashildr married Tomas and stayed with him for twenty years. Their relationship produced three children: Essie, Johann, and Rue. Ashildr chose to leave Tomas because she feared his growing comments about how having three children in twenty years didn't appear to have changed her body, along with questioning whether or not her hair grew, taking their children with her on a boat to England in 1348.
