I am researching my Nelson family from Michigan. One of my great grandfathers Zachariah Nelson (born 1849 in Indiana) has become my brick wall. His death certificate states his father was Henry Nelson who was born in KY. Zachariah (Jack/Zack) married Rosella Cynthia Harrington. Any information would be greatly appreciated! I am also willing to share & exchange photos, records, etc. with anyone interested.
