My paternal grand father 5 generations back was Frederick Fulkerson. He was born in NJ about 1745, went to Abingdon, VA, thence to TN and onward to Livingston Co KY in 1795. He died there with will in 1821. His last wife was Elizabeth Pottinger. All his children were from at least 3 earlier marriages, no names of these wives are known to me. I hope the wife you named is one of these. Your reference to Eleanor Sharp ties it to my Frederick, she is possibly a daughter of Frederick and Elenor Chambers. I know that Eleanor Sharp is a Fulkeson and related to Frederick. While I have no info about your search, I would appreciate all info you have that is connected with Frederick, his wife Elenor Chambers and Eleanor Sharp.
