Thanks for the emails and information, I've enjoyed them.
Assuming that John C. Brewer was the age shown on the 1870 census and not 10 years younger as shown in 1850 and 1860, he would be the son born about 1802 to 1804. Perhaps the children would look something like this:
Children; all born SC:
Zadock 'Zachariah' Brewer, (1795-1804) b. abt. 1798, d. abt. 1866 AR; m: Brumley Tabitha Brewer, (1800-1810) b. 1803, d. 1880 AL; m: Ginn, m: Turner John C Brewer, (1802-1804) b. abt. 1805; m: Jane Joseph Brewer, (1805-1810) b. abt. 1808, d. 1849 AL; m: Frazier Ann Brewer, (1800-1810) b. abt. 1809, d. 1885 AL; m: May Martha Brewer, (1810-1815) d. bef. 1854; m: Whorton; son Joseph Jesse Brewer, (1810-1815) d. bef. 1854; m: unknown; one dau. before 1840 possibly Elizabeth Emaline Brewer, (1815-1820) d. bef. 1854 LA, m: unknown Samuel M. Brewer, (1815-1820) m: unknown; one son before 1840
Neither Samuel nor his heirs are named in the estate papers.Same for Emberson.Nancy Brewer's son, living near John Brewer in 1830, is the same age-range as Samuel and Jesse in 1840 living next to John Brewer.I couldn't find John C. Brewer on the 1880 or later.
