I shall start with Clarence Thomas Barnes (b. 1905, d. 23 Dec 1938), the son of Thomas Elliott Barnes (correct spelling)(b. 27 Nov 1880, d. 3 May 1953) and Clella Canton. I have three wives recorded for Thomas Elliott Barnes including Clella: Hazel Lee Thomas and Fannie Goosey (the widow). There may be another.
The parents of Thomas Elliott Barnes are James Simpson Barnes (b. 25 Sep 1854, d. 7 Dec 1926) and Mary Frances Johnson (b. 9 Jul 1855, d. 27 Jan 1932). The father of James Simpson Barnes is Abraham Barnes. I do not know the birth name of his wife Sarah; however, the widow married again and died as Sarah Foster. My late father worked on this since the 1960s without success. The Missouri death certificate of Nathan Gibson Barnes, brother to James Simpson, gives the name as "Sarah Barnes." Either the maiden name is also "Barnes" or remains a mystery.
Some rare references to this Abraham (1822-1869) have "Abram" and a possible middle name of "Eli."
He fought in both the Mexican War and Civil War (Confederate). He was killed by a team of ornery mules, and is buried next to his brother Milton Barnes at Eldad Cumberland Presbyterian Church in Randolph County, Missouri. (The family was Cumberland Presbyterian until we moved to Moberly, Randolph, Missouri, in 1906 and became Disciples of Christ.) Sarah, the widow, is buried at Mt. Carmel Cumberland Presbyterian Church in Macon County, Missouri.
I have the original photographs of both Abraham and Sarah.
Abraham is the son of Richard Barnes and Mary Polly Tolson who migrated to the Boonslick from Madison County, Kentucky.
Richard is the son of another Abraham Barnes and Tempest "Tempa" Taylor.
That Abraham is the son of another Richard who was born about 1723 in St. Mary's County, Maryland. He migrated about 1744 to Rowan County, North Carolina, and was in Madison County, Kentucky by 1768.
Are you using the McElwee book? It is through to the 1950s. Pflum has done extensive and well-documented research, but stops at Abraham (1822-1869). See also Anderson (who disagrees on a point with McElwee) and, of course, Bryan and Rose.
