Do you know anything about Jonas Chamberlin's son, Joseph, or if he had a brother or nephew named Joseph?. I am a descendent of a Joseph Camblin whose last name has been spelled many different ways. He was born around 1739 in Ireland. He married Eleanor Evans and lived in Washington County, Pennsylvania. I think he may have lived in Chester County at one time because his son David married Sidonia Evans possibly in Chester County. This web site http://homepages.rootsweb.com/~usbios/West_Virginia/Bios/Berkeley/jamesbarrettchamberlin.txt mentions that Jonas had a brother Joseph who went to Pennsylvania. Any information you may have on a possible connection to my Joseph would be appreciated
