I realise most of this conversation is several years old, but I just came across it while researching my family, and I believe I am also related to these Talbots.
I believe that Ann Talbot (bapt 25 Feb 1759) who married Richard Gunton in 1781 is my 5th Great Grandmother.
Anyway, I'm still researching all this, but its very interesting especially the 1784 will of Hardin Talbot.
