We have worked through the Archives in Washington DC and have been able to find lists of his children's names. We have also gone through the county birth and death records in Ohio. Family info indicated that Granville's father was born in Pennsylvania but we have not found any factual verification of that. His son George is my husband's grandfather - his son William and other children were born in Ohio. Later William moved west where my husband George William was born. Any information that would be available concerning Granville and his family would be appreciated.
