I followed the family through the census records, if you haven't done that. Elizabeth H. (Jan 28 1822-Sep 9 1887. is buried in Clinton Cem. Hunt Co. Texas, Ransom died in Hunt County Tx. 7 Feb 1912 Certificate # 4711, did not find his cemetery record. I did find one entry on Ancestry family trees that related to your Ransom Boswell. I canot vouch for anything which is posted there. some are way off, however it will not doubt give clues.
They had Ransom 2 Boswelldied Feb 6 1912 Caddo Springs, married Elizabeth Shaw1822-1887, son of William Boswell 1791-1857 Barton Co. Ga, and Louisa (Lovisey) Whitworth 1795-1876, listed as a child was Vesta Virginia 1869-1962 However they did not list the father of William as a Boswell, but a Cecil, so that is confusing, unless he was adopted or some such thing.
Several has Ransom who married Elizabeth Shaw,as Ransome Perkins Boswell, but I have my doubts on this connection, for I have corresponded with several with that line.
Thats what I looked up this morning for you, hope it will help some. Howard Boswell
