He was the father of Civil War veteran William Spain of the 54th Massachusetts Volunteer Infantry, the first regiment in the United States to enlist men of color during that war.
1870: Urbana, Ohio with his (presumed) children
1860: Urbana, Ohio with his wife and children
He passed away in 1879 due to old age and is buried at Oak Dale Cemetery in Urbana, Ohio.
Because the 1870 federal census doesn't include familial relationships, assuming Maggie and Samuel are his children for now, even though they don't appear in the 1860 census.
His obituary lists him as a servant to President Jefferson, but I'm not sure if Jefferson had any paid servants of color or if all men of color in his service were slaves. I haven't found a federal census record for him in 1850 yet, which might help clarify.
