Baltimore County was created in 1659/60 and was formed as an Original County. The County was named after the City, which was detached from it in 1851. The County Seat is Towson.
The legal origin of Baltimore County is not known, but it was in existence by January 12, 1659/60 when a writ was issued to the sheriff of the county. The County name was derived from the name of the Proprietary's Barony in Ireland in the county of Longford. At the time of its formation, it included parts of (or the whole of) todays: Harford Co., Cecil Co., Frederick Co. & Carroll Co. The original County Seat was at Spesutia Island , it was next located in Joppa Town. As a result of a popular referendum in 1768 (there is a large list of residents signing the petitions, which seems to be about the most complete list of men in the County at the time), the county seat was moved to Baltimore Town. When Baltimore was incorporated as a city, the county seat was moved to its present location in Towson.
Since 1851 Baltimore City and Baltimore County have been two completely separate enities, each with their own records. .
Counties adjacent to Baltimore County are York County, Pennsylvania (north), Carroll County (west), Harford County (east), Anne Arundel County (south), Howard County (southwest), Baltimore City (independent city, surrounded by Baltimore County except to the south).
