Where is New Philadelphia in Pike County in relation to Griggsville Twp., which is near the town of Perry. I have done extensive research on my GrGrGrandfather's family in that area.
Several years ago while in Illinois I drove out to Pike county and went to the library at Pittsfield, which is the county seat of Pike County now. I also drove out to the Griggsville area to look for a cemetery where a number of my ancestors are buried.
I have a Charles Cole in my line and he may have been born in Ohio.
If I can be of any help let me know if any of this rings any bells for you.
Our family also has an active archeological research being done at the present time by the Univ. of Ky, but dates from the mid 1800's.
Wishing you the best in your search.
