The "unfortunate son" Jonathan to which you refer was the son of Alexander Sr. (see his will dated April 16, 1831) not John. I am presuming that Alexander Sr. was a son of John, who left no will. I also presume that Jonathan Sr. was a son of John but others will contend this. He definitely was not a son of the James Esq. who left the will of 1819. I notice that all three of Elihu's sons served in the 2nd S.C. Rifles, Co. E. Did they all survive? Are you descended from one of them?
