They specialize in having an INDEXED cross-referenced obituary collection going back to the early publication dates for the local papers. They also have microfilms available for these papers. They just completed (2010) a project for all the cemeteries in the county which contains GPS locations, which is particularly useful when trying to locate the small and hidden cemeteries in the townships.
