Henry/Harvey Leonard b Apr. 1875

Does anyone have information on this person; Henry or Harvey Leonard born in April 1875 to John Wickoff Leonard and Josephine Miller. Cincinnati, Hamilton Co. OH?
If this is true he is the last male relative of my Leonard line and I am hoping he had a wagonload of male offspring.
This search is very important to me as I was sure my branch of the Leonards had died with Olpha Leonard.
If there was a child born to John and Josephine I would guess his name was "Henry," named after Johns nephew "Henry Ellis" who served as an apprentice under him at the Gazette Newspaper in Cinn. I would also speculate that this Henry was a printer as well following in his fathers footsteps.
He was listed in the 1900 Census;

Line 59, Leonard, John W., Head, DOB May 1836, 64, Married 30 yrs, POB OH, Painter-(Error- He was a printer)
60 Josephine, Wife, DOB Jan 1846, 54, Married 30 yrs, POB PA
61 Henry or Harvey (?), Son, DOB Apr 1875, 25, single, POB PA

John and Josephine were married in May 10, 1865 so unless he is adopted he is their son.He IS listed as born in PA> but we all know how reliable the census reports were.
