Al, I don't know if this helps but I too am researching my Brewer family around Clarke and Jackson co. and here are some of the Brewer families I found in Clarke co. around 1860: Clarke co. Georgia 1860 census:
William Brewer 82 N.C. Eliza A.18 Ga.
W.P. Brewer48 Ga. Sarah Coussons(?) 43? William24 Burwell22 James H. 18 Benjamin 17 Charles C. 12
James Brewer33 Ga. Francis 34 Martha7 Eliza3 Jonah2 infant
My ancestress Eliza E. Brewer b.1832 married John C. Spinks b.1829 in Clarke co. around 1850. If anyone has any info on this couple I would appreciate sharing with them. My email address is firstname.lastname@example.org. Thanks so much. Happy Hunting!Kat Davis.
