In the BLM patent that you cite, it may well be that I have incorrectly identified both the William and the Seaborn, who appear with 1839 (year of death) Samuel Coffman of Sumter Co., Alabama, (place of death.)I, too, had found reference to the contents of Samuel H. Coffman's will in Ms. Gandrud's Alabama records.
Since I made the original post, I have been in touch with Charlene Essary, who has helped work out the two William Brewers of Sumter Co., Ala., prior to 1850--known as Cedar Creek Bill and Holihta Bill.There are also at least two men named Seaborn Brewer.One was a son of "Cedar Creek" Bill, whom I identify as 1852 William Brewer of Sumter Co., Ala.His estate papers, on file at the archives in Montgomery, include a petition from the administrator that says "your petitioner also shows that about seventeen years since Seaborn Brewer, a son of decedent, went to Kentucky on business, expecting shortly to return.He has not been heard of since he reached Louisville & it is supposed he died long since."The same petition, which was not dated, but probably dates from the latter part of 1853 also lists the other children of 1852 William, and does not include a Susan.
The other man, Holihta Bill, is 1858 William Brewer of Marion Co., Alabama.Mrs. Essary had a copy of his family Bible, which not only established his parents, but also his wife and children.He does not have a daughter named Susan.
I checked my records on 1853 Matthew Brewer of Choctaw Co., Alabama, since he came from South Carolina,To date I have found direct evidence for only two sons:1852 Thomas J. Brewer of Sumter Co., Ala., and George W. Brewer.I have no reason to think this is a complete list of names.According to the 1850 census, Thomas J. Brewer had a son named "Seborn" born in Alabama in 1832.Clearly he is not the person named in the land patent of 1837, so he may have been named after an uncle.I suggest this line might be worth examining for your Susan, wife of Samuel H. Coffman.
If you are able to identify the children of 1853 Matthew Brewer of Choctaw Co., I would appreciate hearing from you.If you would like a pdf file containing all of my current information on the Brewers of Sumter Co., Alabama, prior to 1850, let me know by email.I, too, had found reference to the contents of Samuel H. Coffman's will in Ms. Gandrud's Alabama records.Good Luck.L. F. Wright
