It's been awhile since you posted your query but J.G. Beckwith M.D. is Josiah Gale Beckwith, (1803-1871) who married Jane Maria Seymour. He also was a founder of the AMA and had the first pharmacy in Lithcfield. I am researching his son George Seymour Beckwith, (my husband's great-grandfather). J.G. senior and his eldest son Josiah Gale II were CT physicians. G.S. is also listed as a physician and later lived in Pine Plains, NY. George Seymour's story has alot of gaps in it though. Any information would be appreciated.
