Steve:
I recently connected with a volunteer on Find a Grave & she gave me this info for a contact with the Marcellon Cemetery Association:

Karla Walker, N8411 State Rd. 44, Pardeeville, WI 53954. 608-697-0961 (cell)

I haven't tried contacting her yet, If you do, will you let me know. I'm interested in burial records for the cemetery.
