Hello Cousin Brian!
It's so good to hear from family. My line passes through Isaac's sister, Seney Bridgers. She married my g-grandfather Walter Plemmer. Walter Plemmer had a son Percy Plemmer; Percy had a daughter Yvonne Plemmer; Yvonne had a daughter... me - Tomeka Green!
This is an early Christmas present. Seney died when my grandfather was approx. 3 years old so there isn't much known about her or the Bridgers line. What I have is from census records so your assumption is correct. I didn't know anything about Jerry Williams. We must talk more. You can email me directly if you like at tomeka@charter.net.
