I looked at all Miller`s in 1860 Ross Couny census and found only 1 Jeremiah. In Colerain Township , John Miller,jr family. The family consisted of the following: John Miller,jr 39, day laborer, Harriet 33, Jeremiah 11, Melinda 8,Margaret 6, Sarah 4 and Mary 1. All born Ohio. The above family lives next to John Miller 67,farmer and wife Catherine 62 ,both from Pennslyvania. Hope this is the family.
