Nancy, I really do not have anything of real use but may can add to your unknowns.Benjamin and Lydia possibly had two more sons:Orin A. or Aaron (b. abt 1840 MO) & John B. (b. March 23, 1843, Greene Co., MO, married Nancy Hooper July 10, 1867, Chariton Co., MO).My book does not have any information on children for either.I do not know if either moved to TX when the others went at the end of the Civil War.
I do not have enough info on children of Eli and Jess A. to help any.I have the names of the children of Eli (and some of their descendants) and the name of Jesse A.s children.Neither mentions a George but George could be a Grandson of either Eli or Jesse.Eli is a special situation."The word is" that he died at Vicksburg during the war.Another theory is (I think this is the correct theory) that he was afraid to return to MO after the war and went to TX (without his family) and had another family.Many of the exConfederate soldiers were afraid for their life in MO after the war.
A couple other groups had families in TX.By 1790 NC had six (what appear to be seperate) families.At least three of these families had descendantsthat ended up in TX and I believe all by the time of birth of your George.
Again you may know all of this already.My connection is through My wife, Lynn Marley Coffey.Also I have published a Marley family hist book that covers the six marley families of NC;"Marley Families of North Carolina".
