Working on your question regarding the Japs family. I have found a Frank A. Japs, son of William Daniel Japs (1845- 1930) and Christina Singley (1850-1914). Frank is married to a woman noted as Anna H. in census, so the "H" could be for her maiden name.
On one census Frank is described as a boiler inspector. They had two children thru the 1920 census, Wilbur H. and Carlotte E (could be Charlotte mispelled).
Don't know what you are really looking for, but will continue to look.
