George Mangus, Scioto County, OH

Looking for any information on George Mangus, b. 1840, IL. Died 26 Jun 1907 in the Veteran's Home, Milwaukee, WI. He served in the 22nd Rgmt Infantry, (Portsmouth)Ohio Feb 22, 1864-Aug 28, 1865. George married Catharine "Katie" Glenn. After George died at the home in 1907 his effects were sent to his son, Harrison T. Mangus in Phillips, Price Co. WI.

He shows up on the 1880 Scioto County, OH Census (Brush Creek Twp)but nowhere else in IL or OH.

Who were his parents? Where was he born in IL? ANY information would be greatly appreciated.
