I am also a descendant of Abraham Brooks from his son Cyrus who married Sybil Curtis in Lee, Oneida NY. Abraham the father is buried in the Steuben Corners Cemetery along with his son Stephen. Unfortunately, NY was not keeping vital records during and for a long time following the Rev. war. Abraham served in the Revolution along with others who settled in Herkimer and Oneida County NY. Deborah, Abraham's wife died in Haddam, MA and is buried there. I would like any information you have on this line and I will be happy to share anything I find. Cyrus is a mystery and the only place I find him is in the census records and they are not acceptable proof. Cyrus either died after 1835 or moved on. I am working on this constantly so would like to keep in touch with you.
