Thanks to two kind Texas researchers, I have confirmed that John T., James S. and Green J. Pope of the 17th Tex. Inf. are in fact sons of John M. Pope and Rebecca Looters Pope and that the family moved from Montgomery Co., TN in the 1850s to Bell Co., Texas where they appear in 1860 census.Latter census does NOT show daughter Margaret, b. abt. 1849, who I surmise died.
Rebecca survives as of the 1880 census; she is residing with John T., her son (her husband, John M., who would then have been about 78 years of age, apparently died before 1880) and Green J. is living next door.Green married Sallie J. Keys in Belton, Bell Co., TX on 1/24/1867.
The middle brother, James S., does not appear.I cannot say if he perished in the war, or just found a bride outside Bell County or whatever.
Any add'l info or living descendants would of course be welcome.
