Found US Census records pertaining to this couple from 1850, 1860, 1870, and 1880. They started their married life in Marion, Marion Co., OH. Apparently they moved to IL sometime between 1850 and 1860 (oddly enough living in a "Marion Co." there). Daniel Hain died sometime between 1860 and 1870, and his widow Belinda returned to Marion, OH for a time, before relocating again to IL sometime before 1880. She passed the last 20 or so years of her life living with her sister, Mary Wilson, first in OH and then in IL.
