Do you know of any church affiliations for the Keevers in Dauphin Co.? I work in Philadelphia and happen to be a member of the PA Historical Society in town. It is a short walk for me at lunch. They have many church records in their collection.
I do know that my George Keever (1808 - 1861) was buried at Barren Hill Cemetery in Lafayette Hill, PA right outside Phila. The cemetery is part of St. Peter's Lutheran Church. This started out as a Dutch reformed church, and then was shared by both Reformed and Lutheran congregations.
Let me know if you know any other info. about Dauphin Co. I will check out the Historical Society as well.
