Digby Arwell
From Tardis Wiki, the free Doctor Who reference
Digby was a relative of Madge Arwell and her children, Cyril and Lily Arwell.
He was much wealthier than the Arewells, and possessed a large country estate by at least 1941.
Digby, however, had vacated the house to live, according to Lily, "in a home in Battersea". (DW: The Doctor, the Widow and the Wardrobe)
