Jane's Great Uncle David B. Winter

Today Jane told me a story about visiting her great uncle, David B. Winter in the Black Hills.  He was her grandfather's (father's side) brother, and he used to have a summer cabin there.  Jane remembers the sound of the creek next to the cabin when her family took a road trip to Montana and picked up Dave on the way.  My cousin Malcolm has a note on his family web site saying that David had "little black curls" all over his head and that he spent his last years in the Black Hills region.  He was born July 12, 1867 and died June 5, 1950 in Rapid City, South Dakota.  Census shows he was living in Osceola in 1885 and in 1915. (This is probably the same person since Osceola was an important Winter habitation).  Could this be the same David B. Winter of Rapid City South Dakota "who formerly was in the confectionery business and is well and favorably known in this" and was "general auditor for the Rapid [City?] Black Hills and Western Railway company with headquarters at Rapid City" according to the Alton Democrat, June 17, 1911?  Probably not, since although he died in Rapid City, he was probably in Osceola in 1911.  Malcolm Winter's genealogy site is at Winter.
