Sorry I can be of little help here again.....this is all I have of Polly Robinson; B. 1786 in Culpepper co. Virginia - D. 1815 in Butler Ohio. She had at least 2 brothers that I know of - Samuel and John. I do not know her parents or anything of Samuel or John.
But I do have another Charles Robinson who married Mary Ann Yeager. Marry Ann was born in 1815 (daughter of Joseph Yeager and Sarah A. Cheek). That is all I know of this Charles. I also have a Louisa Robinson who married a Lemeul Yeager. Lemeul was born in 1827 in Tenn. I am not sure if any of these Robinson's are related.
