I'm part of an international effort to document Hungerfords and the families that have come from them. I would be interested in knowing more about your line from Orrin Brooks down to the present time.
I can give you a e-mail contact I had but my last communication with her was in 1997. Contact me directly at email@example.com
for that e-mail address.
Regarding Abraham Brooks--I have one reference for you. FHL #1421640 includes "Families of Ancient New Haven," compiled by Donald Lines Jacobus. Page 337 of Vol. 2 states:
Abraham, born 22 Apr 1743 (per Wallingford VR), baptized June 1743 (per records of Congregational Society, Cheshire), died 16 Mar 1805, aged about 63, Steuben, NY (per gravestone record); Census (Bristol) 3-2-2; married 5 Mar 1767 (per Vital statistics, Farmington), Deborah Hungerford. The details re the children--their births--were recorded per vital statistics of Farmington. It also advises that he was the son of Stephen & Hannah (Barnes) Brooks. Deborah was the daughter of Capt. John & Deborah (Hungerford) Hungerford.
I look forward to hearing from you.
