Looking for Moyer of Pennsylvania

I am looking for information on my Great Grandfather Andrew Moyer or any of his decendence. I was told that he might have been a teacher. Sorry I haven't much to go on, My Grandfather was Edward Louis Moyer, born 15 November of 1874, Altoona, Blair Co. Pennsylvania. His Mother was Emeretta Jane Moyer and she and Andrew never married. She moved to Kansas with her brother James Moyer and his wife and they raised my Grandfather to adulthood. Emeretta's parents were David and Rachel (Gray) Moyer.
