Research Library

Located in the old Almshouse, the Historical Society of Baltimore County’s library houses information from every known tombstone in both church and family cemeteries in Baltimore County. Here, you will also find a growing collection of books and maps (copies of some are for sale), census records, marriage records, slave schedules, family histories, ledgers, photographs, clippings, and manuscripts related to the history and genealogy of Baltimore County.
