Husband of Minnie May Collingwood Collingwood and Georgia Estella "Stella" Brown Turk Collingwood. Guardian of Harry Earl Collingwood. Even though Henry's wife "Stella's" name is on Henry's stone, she is not buried with him. Per Henry's grandson, Stella had travelled to California to care for a family member and never traveled east. So when she died there, her family buried her in CA.
