Searching for Information for Mary Ann Kuntz

I have very little information for Mary Kuntz, known fact from family she married John Harmon. They probably were from PA. They had a son King Emanuel Harmon b Aug 1841 in Ohio. King married Mary Ann Selix b 1841 in Ohio. King served in the war, then left and went to I/T in Oklahoma.
I would like more information for John Harmon & Mary Kuntz. Names of parents for each and siblings names for each.
Thanking you in advance,
Maxine Davies
