Birth, Parent-Proof, Designation notes for Michael (Spouse 1)
Kathleen Fite’s Family Group Sheet shows 11 children for Jacob and Elizabeth Martz including son Michael, no birth date given, who married Amanda Berry 25 Aug 1855.
A message board post cites their marriage record as saying he was the son of Jacob and Elizabeth Martz.
So I believe it is well documented that Michael was indeed a son of Jacob and he is designated S1b3.
This was posted in 2000 on the
genealogy.com message board by an unidentified person. My great aunt, Amanda Berry, m. Michael Martz in McGaheysville, Rockingham, VA, 25 Aug 1855. Michael's parents are identified as Jacob and Elizabeth Martz on their marriage license.
Michael and Amanda moved to Kansas and then to Shawnee, OK, where Amanda and her son, Charles Martz, are buried in Fairview Cemetery next to my great-grandfather, Lewis Richard Berry. Charley's wife, Laura, is buried adjacent, also.
I have a photo (ca. 1908) that includes Lewis Berry and his family, along with another family that I assume to be that of Charley Martz, who was his best friend. The Berry family moved west from McGaheysville in 1905 to join Mandy and Charley Martz in Kansas or Shawnee.
Death and Find-a-Grave notes for Michael (Spouse 1)
I don’t know when he died. He and Amanda were in Franklin County, KS in the 1900 Census. It says they were married in 1856.
