As I said in a reply further up the only address seems to be the 1920 one in Lucerne. How about requesting a copy of the death certificate from Pennsylvania Vital Records, you have a date of death or burial. Cost of copy seems to be $3.00 but they have the following criteria -
Access to death records in Pennsylvania is restricted to family members and legal representatives. With your request, include as much as you can of the following: the name on the death record being requested, date of death, place of death (city or county), your relationship to the person whose certificate is being requested, your purpose for needing the copy, your daytime telephone number with area code, your handwritten signature and complete return mailing address.
This is the only address I can find:-
