Gene ~ I don't think I have anything on your Polly, but wondering if she may be a sister to Daniel, who is the first listed in what was sent to me. according to this:
Daniel b. 1794 New Hampshire married Martha Cole (also b. New Hampshire) their children: Hannah, Eliphalet, Eliza, William, John, and Martha Eliphalet (b. 1815 in Massachsetts) named his first child Polly Eliza (b. 1836)
don't know if that'll help you, but I'll keep an eye out. the "possibly" father of Daniel would be Jacob, if that helps.
I found one mention (somewhere on the net!!) of a Jacob McQuaid in N.H. that was killed by indians or something, and that the site was a McAfee/McDuff (?) surname, but havn't found any further info for Daniel's parents. sorry! I'll post here if I learn anything new...
