I now know that Harvey's father was Enos H. Erdman born about 1822 and living in Upper Saucon Twp. in 1870 with Sarah and daughter Catharine. There was also an 18 year old male Erdman (first name unreadable - possibly Isaiah or Joseph ?) attending college listed just above this family in the 1870 census. He could not have been Sarah's son since he was born in abt 1852, 2 years before she had Henry Miller's son, William P. Miller, and she was still single in 1860 living with her brother Willoughby Kepler. Possibly Enos had an earlier marriage since he was about 11 or 12 years older than Sarah. This Enos is not the same Enos that was married to Anna Keck. Both are listed in the 1870 census for Upper Saucon Twp. Anybody know anymore about him?
