Hi,
There is no
Hiram Johnson age 75 +/- 5 years anywhere in the 1880
Kentucky Census. There is a
Hiram Johnson age 63 in District 2,
Boyle,
Kentucky Film T9-0404, Page 345D. Also, I couldn't find a close spelling variation.
There are
Hiram Johnsons born from 1803 to 1807 living in NY, ME, PA and MI during 1880.
Good luck, Mel King
