Which one, Senior? I am not in RI. But it says in a book online called Cowell's Spirit of 76 what year he died. He was a Revolutionary War pensioner and lived to be very old, I think he made it to at least 1830.
Actually I was going through an old guide book at the Hathi Trust. There is a section on Charlestown RI which describes the Narragansetts and there is a drawing of someone called Joe Dent who is obviously Joseph Bent, the lady heard wrong.
