Richard Sorry for delay in answering. My John Buckman was born 19 Aug. 1811 in Lewes, Sussex. His brother Jabez is my direct ancestor. He did migrate on the "Amelia Thompson". He was married to a Martha Borer. They had 3 children, two died on the voyage and the surviving child was William John Buckman b. 1834. I have looked through the descendants of William John and could not find an Edwin Walter Buckman. But like all family trees there is a few missing descendants My email is email@example.com . If you would like I could email a text file of the descendants of William John.
