Seeking information on Mankins/Otis families. I found reference to Rosana Mankins b. 1818 OH in the 1880 census for Hanover, Washington County with her mother Minerva Otis b. 1795 VT. Both are shown as being widowed. Does anyone have access to the 1880 census to see who else is listed with them on the census. Or is anyone else familiar with these lines. Thanks!
