I don't find a child named Rueben associated with this Alexander family. I may not have all information on this family and the other people establishing the church, but I have quite a bit. I'll start at the top and go down the Oak Grove list.
Samuel Alexander, the son of James Jr. and the brother of Lawson, was married to Elizabeth Hinton (Logan County, KY). She is probably the seventh person on the list.
I don't know who James Lackey or Jane Lackey, fourth from the bottom, was, but, in 1840, Hannah Lackey apparently lived next door to Jane Barry Alexander. Nor do I know who Rachel and Sarah Breazeal were; however, the Breazeal family and Alexander family intermarried and probably traveled together from Roane County, TN, to MO.
I believe that Violet Elliott was a sister of Jane Barry Elliott and that she is buried in Crandall Cemetery.
Margaret Alexander was probably Samuel's and Elizabeth's daughter Margaret, who married Samuel Hankins a few months after this document was issued. They migrated to MO.
I said previously that Jane B. Alexander was Lawson Alexander's widow, Jane Barry Elliott Alexander because Jane B. was the way she normally gave her name; however, this Jane B. may have been Jane Brittain, the wife of their son William Lawson Alexander, the person reported as "ruling elder." William Lawson and Jane had just married. I'm unsure exactly when Jane Barry Elliott died, although a descendant will have that information.
I don't know anything about James Ray although the name seems familiar.
Louisa E. Alexander was the daughter of Samuel Alexander and Elizabeth Hinton and married Thomas Rodgers in 1860. He was a widower, and I don't know that she was not also married previously. They migrated to MO.
Jane A. Alexander was the daughter of Lawson Alexander and Jane Barry Elliott and either never married or married when she was elderly.
I don't know about Ezra Liles; however, there were Liles children in at least one of these Alexander families, and court records show guardianship or some such.
I don't have James Spence; however, Lawson's sister Margaret Alexander married Robert Spence in 1818. Margaret--and Robert, if was still alive--migrated to MO after 1850.
I don't have anything on Sarah Osborn.
I have the one listed as Emily H. Alexander as Emily M., but I could be wrong. She was the youngest child of Lawson and Jane Barry Elliott, and she either never married or married when she was elderly. She and Jane made their home together after their mother's death, and one of them reportedly married late in life.
I don't know who the McClures are; however, they are supposed to be related to the Elliotts. There was also a McClure family (related to me) from the SC area from which the Alexanders migrated, but I doubt they are related.
I don't have anything on the Taylors or Margaret Wright.
Samuel L. Alexander was the son of Samuel and Elizabeth. He later lived in AR, and I've been told that he died in MO.
Robert Box was a neighbor of Jane Barry Alexander in 1840.
I'm not certain which Brittain William was, but he may have been Jane's uncle. Her father died before 1848, and, in that year, her mother Margaret married Lawson's and Samuel's brother Ezekial. Ezekial and Margaret migrated to MO some time between 1850 and 1860.
E-mail me if you wish. If you have anything tying the Rays to this Alexander family, let me know. For what it's worth, about half the time this family and the branch that went to western KY and TN reported their parents' birth places as being NC instead of SC. On one census, four sons living near each other reported three different combinations of birth states for their mother and father, and the fourth probably got everything correct only because he lived with the parents.
