Yes I am a descendent of several of the Brewer lines.
Phoebe Brewer Carter, daughter of Braxton, was married to George Carter, and their oldest daughter Sara Carter was the 2nd wife of Morgan Brewer.
We have not been able to find a death date for Braxton. His birth date, I believe is on Census Records. Also we have not been able to find a burial site.
One of Morgan's younger sons is Braxton Brewer who lives in Indiana.I have always believed he was named after the "old Braxton". But I guess we'll never know.
I and some other Carter descendents have searched for Braxton's death date or record in several places, including the census (microfilmed from the original) records and the minutes from Brewer's Chapel Church which are on file in a local library. He is listed in the census records as living with George and Phoebe (Brewer) Carter, I guess in his older age. If you are able to find any information regarding Braxton's dates or death records, I would love it if you could share information with us.
