Yes Cyrus is one of Abraham Brooks sons as is Stephen. Abraham and Stephen are buried in Oneida County, I believe in Steuben Corners Cemetery. Cyrus is, according to some sources, the husband of Sybil Curtis. It is very difficult to get information from New York state as records were not required until the 1880s and these people lived in the 1700s to the mid 1800s. Sybil is buried in Lee Center Cemetery are related lines from Samuel Wright, Efraim Curtis, James Young who's wife Hannah is descended from the Fuller and Rogers Mayflower passengers.
