First there is no 1890 Census except in limited info. There was a fire where the records were kept and in process of putting fire out, the documents were water logged. An attempt was made to save these and seperate when dry but some important person said to destroy them as they were not worth saving. Alas they are gone. A few remain ,not many. I checked Ross County birth and death records for a Harry Manns , none showed either way. Therre was a set of unnamed twins died at birth but parents were not listed , this was in 1893. I did find George W. Manns in 1920 Henry County, Reed Crek , Virginia, ED118 page 6A. He is 54 , Eliza is 55 and kids start at age 23 and down.No trace of Harry. There is also an 8 year old George Manns in this Township on another page.
