Harmon Hockenberry, Franklin Co. Penna

I am attempting to continue my family history reseach on the Hockenberry's of Path Valley. I need help. My G-Grandfather was Harmon L. Hockenberry Jr. (June 10, 1872-April 14,1925) married to Martha E. Hockenberry(see where it starts to get difficult) 12 Nov 1868- 23 April 1936. There children were:Edith M, Annie Belle, Charles Franklin, and sylvester.
Harmon Jr parents were: Harmon Hockenberry1840? to bfr 1900 and margaret Kell.
Martha's parents: William Hockenberry 1833-?
Eliza Hockenberry?? 1834-?

Ican use any additional help to sort out these Hockenberry"s.
