It seems likely that the Zylevster Hescock listed at father would be my ancestor Sylvester Hescock of Townshend, VT. I don't have too much information about him or his wives. (he seems to have been married more than once, and I do not know which was the mother of Lorenzo, from whom I am descended.)
Sorry, it's not much. I have yet to make it to Townshend to research records.
