Hi, I'm a research volunteer, not related.
Looks like Clinton was actually born in Indiana. He was only in Wisc for awhile, Ruby was born in Winconsin. There is an obit on findagrave.
His father was probably Herbert, 12 Aug 1881 - 1964. Not sure about the mother. the 1920 census shows Herbert Smith, 38, Ida 34, Clinton 16, then a big age gap to brother Carroll 5, and sister Elizabeth 1.
Herberts father was probably Rufus and mother Sarah (Bartlett) They had at least 9 children.
Smith's seem to have stayed in Delaware County.
