Was one of Jemima Harris' sons named Harrison Llewelyn Harris?

I am not related (that I know of) but I love cross referencing names through one of my very favorite online books, the History of the American Negro and His Institutions, and here is a mention w/a Jemima Harris from Fairfax: http://books.google.com/books?id=_ToTAAAAYAAJ&pg=PA18&dq=Harris+L.+Harris+negro+and+his+institutions

Much success...
