Have you seen the book, The Burnett Genealogy? It has the ancestry of Robert Knox Burnett, born in 1936, who was a descendant of James and Sarah Bradley through their daughter Rhoda Bradley Skinner. The genealogy begins with the immigrant, Isaac Bradley, born abt 1650 in England and John Chidsey born "probably" in England in 1688.

One bit of info about James Bradley is that he died in Jericho, Vermont in February 1806, possibly at the home of daughter Rhoda Skinner
