Boundary Changes

Baltimore County was an original county in Maryland, chartered out of the wilderness. There is no existent charter or other act for the county, however, other data indicates that the county was formed about 1659.

The following maps were prepared from the base of a 1906 Atlas map to show the changing boundaries of the county over time. In the 17th century, the boundary between Maryland and Pennsylvania was disputed and not settled until the Mason-Dixon Line was surveyed in 1763-1767. Baltimore County claimed boundaries encompassed parts of Delaware and Pennsylvania in the 17th century. The western boundary of Baltimore County was not well defined until Frederick County was formed in 1748, parts of Frederick County at that time were considered Baltimore County, with most of Frederick County coming from Prince George's County (which encompassed most of Western Maryland). Over the years the size of Baltimore County has decreased to its present limits, with the last major change coming from annexation of a large area by Baltimore City in 1918.

Hundreds & Parishes

When researching Baltimore county before ca 1820, you will encounter two terms referring to an area of land. One of the terms is Hundreds and the other is Parishes Hundreds as a political subdivision date back to the Roman occupation of Britian. Their are several variations of the orginial meaning of the term. The most commonly accepted is that is was an area that contained 100 families. Another variation is that it was an area that was large enough to raise an army of 100 men. From the late 1600s to early 1800s in Maryland the term was applied as a political subdivision of the county primarily for tax purposes and judicial affairs. The latter being that there was a constable appointed for each hundred and a justice of the peace for each hundred. The 1790 and 1810 Federal census for Baltimore county are at least partially broken down by hundreds. The equivalent term today for a hundred is an election district within the county. Although Maryland was founded by Catholics (the family of Lord Baltimore), its religion was dominated by Puritans in the 1650s and then later the Church of England. In June of 1692 the General Assembly passed an act that essentially established the Church of England as the "state church", required the establishement of parish boundaries and also required each parish to establish a register of births, marriages, and deaths within the province.

When Baltimore county was first settled, there were no roads, except a few indian paths; thus, travel was mostly by water, and you will find persons styled in terms of where they lived. For example in early deeds, people are styled as: William Boulton of Bush River, Richard Ball of Patapsco, John Lee planter of Bush River. The early Hundreds were thus often named for rivers. When Baltimore county was fist formed, its boundaries ran from the ridge dividing the watershed of the Magothy and Patapsco Rivers around to the Sassafras River. Thus it included todays Cecil county, and Harford county, parts of Carroll, Anne Arundel, and Howard counties. Also since the early boundaries were not fixed it probably also extended into Delaware and Pennsylvania. Cecil County was formed in 1674 at which point the northern eastern boundary of Baltimore county became the Susquehanna River. A formal boundary between Baltimore and Anne Arundel county was initially laid out in 1698.

By 1698 is appears there were three hundreds in Baltimore county, the Patapsco Hundred (which ran from the south side of the Patapsco River to the north) the Gunpowder Hundred, and the Spesutia Hundred. The original county seat was at Spesutia Island off the Bush River. Apparently there was a town of Baltimore in this location in 1683. In 1707 the General Assembly directed that a twon be erected on 50 acres called "Taylors Choice" and that the county courthouse be erected there. This land was off the Gunpowder river. However in November 1712 an act of the Assembly directled that the courthouse be erected in the town of Joppa.

There were three parishes established in Baltimore County in the 1690s. These were St Pauls, St Johns, and St Georges. The parish boundaries roughly corresponded to the boundaries of the three hundreds:
St Paul's Parish was the Patapsco Hundred
St John's Parish was the Gunpowder Hundred
and St George's Parish was the Sesputia Hundred

In 1727 the Boundary between Anne Arundel and Baltimore counties was changed so that all land on the south side of the Patapsco river was to be in Anne Arundel county.

As the county's population grew, new hundreds were created. Also because of the distances to the churches, "chapels of ease" were built. These later became their own parish. St Thomas Parish was created in 1742 and the chaple was built near Garrison Forest as part of St Paul's Parish for the western part of the county, and St James was created at Monkton in 1750 as a chapel of ease for St John's Parish. St James was recognized as an independent parish in 1777.

From the 1737 Tax lists: the Hundreds and Parishes for Baltimore county were:

On 2 March 1774, Harford county was created out of Baltimore county. with the Little Gunpowder river serving as the dividing line between the two counties.

In the Federal Tax assessment of 1798 Baltimore County was divided into the following hundreds:

  • Patapsco Lower Hundred
  • Patapsco Upper Hundred
  • Middlesex Hundred
  • Soldiers Delight Hundred
  • Back River Lower Hundred
  • Back River Upper Hundred
  • Middle River Lower Hundred
  • Middle River Upper Hundred
  • Gunpowder Uppper Hundred
  • Mine Run Hindred
    • North Hundred
    • Pipe Creek Hundred
    • Delaware Lower Hundred
    • Delaware Upper Hundred
    • The town of Baltimore

    The other major boundary changes occured in 1837 with the formation of Carroll county from the western part of Baltimore county and the eastern part of Frederick county and in 1851 with the formation of Baltimore City as an entity separate from the county and in 1836. The county also lost land through annexations by Baltimore City, particularly in the early 1900s.
