I checked the 1850, 1860, and 1870 Ohio Census Indexes, for Benjamin Roberts. While there were quite a number of Benjamin Roberts' living in Ohio, there was only one living in Huron County, at the time of the 1860 and 1870 census, and three living in Huron County in 1850.The 1860 and 1870 Indexes listed the following family living in Huron County, Fairfield Twsp.:
1860 Census (enumerated July 18,1860) microfilm page 338 Ben F. Roberts, age 44, Drover, born Virginia Sarah J., wife, age 39, born Pennsylvania Mary, age 8, born Ohio
1870 Census (enumerated July 8,1870) microfilm page 274.B.F. Roberts, age 52, Works in tin shop, born Virginia Sarah J., age 50, Keeping House, born Pennsylvania Mary J., age 17, At Home, born Ohio
The ages in the 1860 census don't seem to add up, but it is undoubtedly the same family. The 1850 Ohio Census Index lists three Benjamin Roberts. My local library does not havethe actual census microfilm for the 1850 census, but the following is the index information.
1850 Ohio Census Index Ben F. Roberts, Huron County, Norwalk, page 75 Benjamin Roberts, Huron County, Fairfield Twsp., page 333 Benjamin Roberts, Huron County, Townsend Twsp., page 786
If you believe that this is the family you are seeking, I may be able to find additional information on my next visit to the library, if you wish. Although I don't live in Huron County, my local library has quite a bit of information on the county.
