Hmm.This is interesting.I'll start checking CT for Bethuel and Flavia.I don't have her last name either, but have a tentative last name for Hawkins wife as Martha CORBIN.
As for the two Hawkins'.I've been looking into where the name Hawkins comes from without much luck.Perhaps a maternal relative?It might be a clue to Flavia's maiden name.It is difficult to believe there were two men born at the same time with this unusual name.Do you know what year your Hawkins married Damaris MESSENGER?and where they married?It is possible that this is the same Hawkins and two marriages.
Bethuel and Flavia are said to have the following children:
Hawkins B. (middle name probably Bethuel) Stephen G. Esther Joel Flavian
Hawkins and Martha had the following children:
Daniel Catherine Nathan Bethewal (My line) Issac G. Mary Jane William D. Martha C.(middle name could be Corbin after her mother)
