Russell, Delighted to see your posting! I recently began a search for ancestors of my maternal grandfather, Robert Lee Jarman B. 14 Feb 1888 (possible 1889 or 90).His Mother was Rose or Rosanna.
I know he had a brother Samuel Jarman, who raised his family in Newport News VA.Their father, was Tom, probably NOT Jarman but Duvall/DuBois and probably the owner of the property they occupied/worked.
There were other older siblings, including sisters Hattie, Clara, Clem and Walter, who's father was different than Robert and Samuel, but we are unsure of his name or their Mothers name.
Little else is known.
Robert came to Onslow Ct near Jacksonville working/laying rails I believe. He met and married my grandmother, in then, Camp Perry, where they raised their family as a tobacco farm owners on land left to my grandmothers parents, Edmund & Susan Cox.
Awaiting birth documents from the state but that time period documentation is more through census and/or bible records - that is how we know his sister Hattie was born 7 Oct 1881.
Tracing this ancestry will be a difficult one but any leads are welcome and hopefully may even provide additional insight for your text.
