I was wondering if some kind soul could please check the Stephenson County Cemetery Inscriptions for:
Christian Miller/Mueller (1815-1892)
and his wife,
Dorothy "Dora" nee Oberdieck Miller (1820-1897)
I do have access to Volumes 4 & 5, so I've already checked them but without result. This Miller family did live in Harlem, so they could be in Volume 3. However, they also lived in the Third Ward of Freeport.
The year of deaths *should* be correct as the source was a county history from 1903. The years of birth were calculated from their respective ages at the time of death, so I expect them to be off at least +/- 1 years.
