I was visiting the website of the Pennsylvania Historical and Museum Commission and accidentally found record group RG-14: Records of the Department of Internal Affairs Record of Marriages, 1885-1889. This is a digitized index of marriages across the state of PA for the specified 5 year period. Unfortunately, it does not have a search engine, but if you are willing to page through the images, you may find an elusive marriage record. Separate indexes for brides or grooms and covers the whole state. http://www.phmc.state.pa.us/bah/dam/rg/di/r14-25RecordMarriages/r14-25MainInterface.htm
