Possibilities on familysearch.org. Philip and Julia (Noman) have son Leo b. OH in 1880 Census.
A Leo Huber b abt 1877 married Bertha Hummel b. abt 1880, both of Portsmouth OH married 1899 Campbell, KY.
Bertha Hummel listed in 1880 Portsmouth, Scioto, Ohio Census b. 1879 age 7 mos no other household members? And a George Hummel age 27, living nearby is listed as widowed? There appears to be a lot more on this particular George on census data.
Need a lot more to connect these dots.
