Gresham's mother died of cancer in 1960, and Lewis continued to raise Douglas and his elder brother David. At Lewis' death in 1963, his estate went to his brother Major Warren Hamilton Lewis, a renowned scholar of French history. The Major in turn passed the estate to Douglas and David ten years later. Douglas Gresham acknowledged in a 15November 2005 interview on NPR that he and his brother are estranged, although in a 4 December 2005 interview he did say that they are in email contact. Douglas Gresham is a Christian, as were Lewis and his mother, while David returned to the Orthodox Judaism of their mother's ancestors while still a child in Lewis's home. Lewis made an effort to find kosher food for him.
