Thanks for info and I will let you know if I happen to find anything else.
As for the location of the Rumburg Family Cemetery, it's on Rt 19-21 between Wolf Creek and Camp Creek in Mercer.
For a listing of all buried in this cemetery would suggest you check out a copy of the 1984 edition of "Mercer County History" pub. by the Mercer Co. Historical Society, Inc. and available at several libraries, pg 106.
