I'm afraid I don't have any provable info on my Mary and John Tucker. Their son was Philip Tucker, born 1809 in Malborough, Devon, England. He married Elizabeth Date and they had a son named John Tucker, who was my gg-grandfather. He was born 3 April 1836 and moved to the US where he settled in SC and married twice. I have had a very difficult time with Mary and John Tucker, because she was Mary Tucker before she married, so not having middle names makes it extremely hard to prove. I do know that there was a John Tucker who moved to Ontario, because he has surfaced several times when I was researching my John Tucker, but as far as I know, my John never went to Ontario.
