I do not have a Sarah Ann Brockman as one of Thomas Brockmans children. See below.............I do find her in the Russell Co. 1860 census with John Antle and it indicates she is 23 yrs old which would make her born sometime around 1837. I did not find a marriage for her & John in Russell Co., but did find one for Rachel Brockman to George Antle......in 1863. IGI indicates Sarah & John Antle got married about 1850.......Of course, it could be way off. Marilyn
