My Grandfather Archie Buhl Canfield was born in Milan Michigan. He was one of five boys born to George Canfield and Cora Watson Canfield. George was the only child of Lemuel C Canfield and Laura S Gay. Laura and your ancestor Prudence were among several children of Isaac Gay and Prudence Buhl but the only two born in Michigan. I have some additional information, but not well organized. Hope you find this useful.
