The Willard Green that lived in Kimballsville,Rich County, Utah - wife Rosamond Farnum Sprague is on my husband's pedigree - 2nd great grandfather. He was born in Lisle, Broome, New York 3 May 1819. Willard's mother-in-law, Barbara Sprague died in Rich County 6 Sep 1874. He died in Preston, ID on 10 Nov 1892. Ebenezer Green, his father, died in Chatfield, Minnesota but I don't know if he ever went to Michigan. Sorry I can't help you more.
