Hagadorn-Schoharie County, NY mid-late 1800s

In 1860 in the town of Gilboa, Schoharie county, NY there was a family by the name of Hagadorn. In the family was:

Orson 26yrs
Nancy 23yrs
Hellen 2yrs
living with them is Gemima(Jemima) Richmond 12yrs.

In 1870 Orson Hagadorn and family are living in Durham, Greene county, NY. Jemima is married in 1870 and living with her husband Alexander Smith. I am wondering if Nancy's surname was Richmond.Also looking for Orson's parents, siblings, and dates/places of death. Thank you.
