William Hubbard, 1727-1771, was my 5G grandfather. He was supposedly married to Mary Peck, unknown parentage; their daughter Mary Hubbard married Oliver Burr in New Haven, 1775. William is supposed to be the son of an Isaac Hubbard, 1693-1771, Connecticut? and Bethiah Goldsmith, 1698-1770, daughter of Thomas Goldsmith and Bethiah Terry. But who was this Isaac? None of the Isaacs I've looked at seem to fit in. I rather gave up on this some time ago, but this group has reopened my interest.
