I had seen your query some time ago, and knew I had read the history in a book called "Slaves by Choice" by Sims. I had given the book to my daughter and did not have access to it, but guess what? I ran into Mr. Sims in the grocery store, and asked him about the history and he said that Ben Smith had a plantation and had two sons Ed and Robert. As soon as I get the book back, I will read the history and get back in touch with you. Mr. Sims (I cannot remember his first name at the moment) lives at Smithridge and is a retired teacher. He asked me where were you living. I hope I can help.
