A very distant Brooks cousin of mine recently sent me some information that might be of help.I have not verified any of this and you probably need to take it with a grain of salt, but he states that Joel Brewer who was a judge in Cedartown, Georgia was a son of Benjamin Brewer, who was a brother of Rachel Brewer who married Elijah Brooks.(Joel would have been, therefore, Rachel's nephew.)Rachel was born about 1797.My informant gives Rachel's father's name in two places -- first he says he was "William," second he says he was "James."No sources were named.
I wish I had more information for you but perhaps this will give you some leads.Good luck.
