I am also looking for the connection back to England. When I went to Ireland, The Historical Research Ctr. gave me information that there were Twibells back in the17th century in Yorkshire England. They spelled their names Twibill, Twybell and Bell. In my info. from here it did say that John's father was in the English military. A lot or most of the birth records in Ireland were destroyed, and there is conflictiing information as to where he was born either Monahan county or Cork. I am looking for the same ancestor.
