Benjamin Welch, Master Car Builder
My great-grand uncle is Benjamin Welch. I don't know much more than you insofar as what you have published. My mother Barbara (WELCH) Lifschutz is still alive as is my father, Joseph Lifschutz. I have copied this message to my father (and sister) in the hopes that they may have some more info for you. My mother does not use email and I will talk to her in person.
FYI. I am traveling next month back to Peaks Island, Maine an early residence of Benjamin or at least his father.
