I just started looking for information on James Edward Lamb and saw your post from 2007. Are you still looking for information on him? James Edward (Ted) was married and he and his wife Bessie never had any children.
"Cousin Ted" was related to my husband's grandmother, Blanche Augusta Lamb who was apparently a half sister to Ted's father.
John C. Amberman (Captain Jack)was married to Elizabeth Lamb according to the information that I have. I haven't had time to search for more information yet.
Ted was born in Australia in 1902 and apparently on the ship with Captain Jack and his wife Bessie (Elizabeth) as early as 1907. Captain Jack didn't have any children of his own.
Ted became a naturalized citizen in 1945 or 46. He lived in Jamacia Plains, MA and we visited him in the 1970's. He was a very nice man and loved children.
This is all I have right now. I just started looking.
