IF he served in a SC unit, he would be eligible for a pension regardless of the State living in. Because J.H. Hudson says he is not eligible tends to indicate that he was not "officially" enlisted and served in a capacity of a "camp follower" or unofficial aide-de-camp. But it is obvious that he was there with the 26th SC Inf. Did you say what his wife's name was? That might be another lead to follow.
