- Her name is also Childress. Therefore, JL Sr.'s notes say that "James K. Polk—married Sarah Childress of Rutherford County—Jan. 1824. She was a sister of my great-grandmother who married Abner Wimberly of Tennessee." This was according to the "Polk Book" in the Maryland Historical Society.
According to a letter to his sister Cornelia dated Sept. 8, 1934, JL Sr. says that "Mother told me that his wife, who was a Miss Childress, was President Polk's wife who I know was a Miss Childress and very strong, fine woman. The late Captain George Polk who was either a nephew of Leonidas Polk or the President, told me once that was not the case as the wife of President Polk had no sisters. I have never been sufficiently interested as to hunt the matter down as it would be purely reflected glory."
Not only that, but it's not likely. I'm not sure whether or how Elizabeth Childers/Childress was related to Sarah Childress, the wife of President Polk. Her parents were Joel Childress and Elizabeth Whitsitt.
There is an Elizabeth Wimberly (21 Dec 1796-29 Aug 1869) buried in Marysville Cemetery, Union Co., Arkansas. Her daughter Eliza's husband worked in Arkansas for a time, but it's a very outside possibility that this is the same person (findagrave.com).
