I have Polly C. Longest married to a "James" Dicus b.1827 TN .
James is the son of Ozier and Pheriba Dicus.At one time I found a record of Sabrina Gregorys family but would have to dig now to find that reference again. Someone in the Gregory family wrote a book on that family, I found it in the Heritage Quest databases. I am not even certain I copied that reference.
It will take me a few days but will try to get back with you if I do find it again. Below are a census record for James & Polly. James married a second time to Sarah Wilson Young in 1859.
