Your note is a bit old but perhaps you still look for messages. I just found time today to do some more online research for my family tree having been "tinkering" for many years off and on with it. However today I did find a treasure chest of information about my William Tiffe Summerville connections.My maiden name being Summerville - William Tiffe Summerville is my (4 great)great great great great paternal grandfather.
Have you found answers? Have you connected with other family members who are or have researched this line? I would love additional information of course and I am willing to share what I do know. Just let me know.
