Find Cyrus Jr.'s probate records in Pennsylvania to find a list of his children.
I'd contact the Pennsylvania, McKean County genealogical and historical society and ask if they have a local death index, indexed newspaper death notices and inventoried cemeteries.
After you find a better date about when he died, look for his probate records. Successful Seaerching!
