I would think that he might have been accompanied by a few friends or associates......study the records of his unit........I'd say there are several more....try the Miss. River counties, Keokok.......Chariton & Grand River counties........Try the 1860 census see names of Men born in Missouri and not in IA census 1850......Broadfoot has a million + names to look thru........good luck.......find any CSA buried in Iowa, let me know
