In my research on another Dinwiddie line, I found the following info regarding John Dinwiddie and his wife Sarah Martin. I will share copies of the original that I have in my files if you contact me off list.

RW Pension file w 8671 from Lincoln County, KY
John Dinwiddie b 7/1/1759 place not stated
married in Amherst County, VA on 1/2/1787
Sarah Martin b 4/25/1760 place not stated

Children born to them

Nancy born 4/13/1788
Polly " 10/13/1792
Rhoda S " 6/23/1795 m an unidentified Martin

One of the other daughters married Henry Small as he is mentioned as son-in-law in the application.

I'd like to connect my line of James Dinwiddie if there is documentation.
