I am the 2nd great grand nephew of Martin Grun. A German immigrant, Martin fought in the Civil War on the side of the Union (Company A., Wisconsin 22nd Infantry Regiment). Family lore also says that he fought in the "Arkansas Indian War" and was killed in 1871. I can't find any record of this. Does anyone on WT have a source where I could verify his service and death? I am starting to think that the location of his death may have been Kansas and not Arkansas.
