Genealogy of Pennsylvania
with a special emphasis on Philadelphia
by
Jane Adams Clarke

Since Pennsylvania's formation in 1682, the basic political
and administrative division of county organization has been
by township, boroughs and districts. Taxes were collected by
townships.

Records such as land and probate contain references to
townships. These important documents are in the County
Courthouse or the County Archives of each county.

Boundaries for counties, as well as townships, have changed
over the years. If the jurisdiction for tax and land records
is not known, it is easy to lose an ancestor. You could be
knocking on the wrong courthouse door!

When Pennsylvania was first established, there were three
counties, Philadelphia, Bucks and Chester. From these three
counties gradually evolved the present day sixty-seven counties
comprising the Commonwealth of Pennsylvania. There were also
the three so-called lower counties: New Castle, Kent and Sussex,
which became the State of Delaware.

A study of the changes in Philadelphia County follows:
In 1752, present day Berks County was created from part of
Philadelphia and part of Lancaster County. (Lancaster had been
taken from Chester County in 1729.)Montgomery County was
created from Philadelphia County in 1784.

So, if your ancestor owned land in Frederick Township,
Montgomery County in 1785, it is necessary to go to Philadelphia
to find the original deed for the property he might have bought
in 1782!

In 1854, the City and County offices of Philadelphia were
consolidated. The boundaries of Philadelphia since 1854 for both
city and county have remained the same and, from that time on,
Philadelphia was divided into numbered wards. The townships,
wards, boroughs and districts that were in Philadelphia County
between the formation of Montgomery County in 1784, and the
consolidation of the city and county of Philadelphia in 1854
became forever lost.

The original townships, within the present boundaries of
Philadelphia, were: Germantown, Roxborough, Bristol, Oxford,
Lower Dublin, Moreland, Byberry, Northern Liberties, Blockley,
Kingsessing, Passyunk, and Moyamensing.

Moreland Township was split in 1784 when part of it was
included in Montgomery County - there was then a Moreland
Township in Philadelphia County, and a Moreland Township in
Montgomery County.

Over the years, these townships of Philadelphia County were
further divided into townships, boroughs and districts.

The original City of Philadelphia, which was a town until 1691,
covered the area between present day South Street and Vine
Street, and the Rivers Delaware and Schuylkill. Just prior to
1854, the old city contained the following wards: North Mulberry,
South Mulberry, North, Middle, South, Locust, Cedar, Spruce,
Lombard, Upper Delaware, Lower Delaware, High Street, Chestnut,
Walnut, Dock, Pine and New Market.

Pennsylvania Line, published by the Southwest Pennsylvania
Genealogical Services
in Laughlin town, PA, is helpful in
determining the genealogy of townships in Pennsylvania;
however,only townships that exist today are included. Therefore,
these lost townships of Philadelphia are not shown. This can be
confusing.

For instance, there is a Bristol Township in Bucks County. If
you are looking for an ancestor from Bristol Township you might
pick up the one in Bucks County, as it is the only one that
appears in reference sources. In reality, your ancestor could
have been from Bristol township in Philadelphia County!

Genealogy of Philadelphia County Subdivisions, by John Daly and
Allen Weinberg,
published by the City of Philadelphia Department
of Records and republished under the title Philadelphia County
Political Subdivisions, by Area Keys,
contains a series of maps
that are extremely helpful in analyzing the boundaries through
the years in Philadelphia. Not included is information on the
portions that became Berks and Montgomery Counties. The original
publication is no longer in print, but has been reprinted by GSP
as "Special Publication no. 6" under the title Philadelphia
Maps, 1682 - 1982: Townships - Districts - Wards.

wills probated in the county where they lived, they did not
always do so! If you can't find the records where they should
be, check neighboring counties.
