Parent-Proof notes for Sarah Marguerite Hart
Her full name and maiden name come from the delayed birth record of their son Lewis.
Birth, Parent-Proof, Designation notes for Dennis Jackson (Spouse 1)
We know Dennis as Richard’s son from his presence in his father’s 1850 and 1860 Census household. His full name comes from the Iowa delayed birth record of Lewis Melvin Martz born 3 Feb 1880 who said his father was Dennis Jackson Martz born abt 1848 in Summerset (sic) Co, PA and his mother was Sarah Marguerite Hart. Dennis is designated H2a6b.
Relocated and Census Tracking notes for Dennis Jackson (Spouse 1)
By 1870, he had left Pennsylvania and moved to Coldwater, Butler Co, IA where he was said to be a teacher and living with Jacob and Catherine Noss. Their immediate next door neighbor was Jacob R Martz, Dennis’ brother, also said to be a School Teacher. (I also notice several families named Sturtz living nearby.)
And by 1880, he was married, living in Nebraska and was a lawyer. He was listed as D J Martz in 1880, but the initials of his wife, S M, and the presence of son Lewis M age 4 months — totally consistent with Lewis’ delayed birth record — confirm it is Dennis.
