Hi Bob, I'm hoping you have info on the uncle Jeremiah. I am searching Sarah Jane Carnell (multiple spellings)b- 10 nov 1860 in Carroll Cty, TN., d- 22 feb 1955 in Crowell TX. I recently received her death certificate showing father's name as Jerry (I believe this is Jeremiah) Carnell, mother's maiden name as Brikeen.
I've been looking at various "trees" and have seen all of the names you state mentioned.
I have information that indicates Sarah was the daughter of William David and Martha Jane (Eubanks) BRECHEEN (source: U. S. Census, 1860, Henderson Co., TN). She's listed as S. C. BRICKEEN, age 1 (b. ca. 1859), parents W. D. and M. J. BRICKEEN. Two of her uncles were Jeremiah CARNAL and Iseriah CARNAL. William was the son of Jesse and Susannah (BRIDGES) of Maury Co., Henderson Co., and Carrol Co., TN. Let me know if you want more information, and I can send you a summary of my information and sources for the BREECHENs.
