Montgomery County, PA, was created on September 10, 1784, out of land originally part of Philadelphia County. It is believed to have been either named in honor of Richard Montgomery, an American Revolutionary War general killed in 1775 while attempting to capture Quebec City, Canada, or for the Welsh county of Montgomeryshire (named after one of William the Conqueror's main counselors, Roger de Montgomerie), as it was part of the Welsh Tract -- an area of Pennsylvania settled by Quakers from Wales.
As of 2000, the population was 750,097. A 2008 U.S. Census estimate placed the population at more than 780,000, making it the third most populous county in Pennsylvania (after Philadelphia and Allegheny counties) and the 69th most populous county in the United States. The county seat is Norristown.
Sussex County, DE, was first settled by the Dutch in the early 17th century. So is the birth of Delaware history, as the town of Lewes was founded as a Dutch whaling colony in 1631. That first European settlement gives Lewes its claim to fame of being the 'First Town in the First State' and makes Sussex County the birthplace of what would become present-day Delaware.
Sussex County is named for the County of Sussex in England, which was the home of Colonial proprietor William Penn.
Today the County is diverse in both its riches and its lifestyles. It is home to numerous seaside resorts, small towns, industry, and agriculture. Along the coast, tourism is strong in the quaint and tony resort beach towns. Western Sussex County, meantime, is the backbone of Delaware's agriculture industry.
New Castle County, DE, is the northernmost of the three counties of the U.S. state of Delaware. The county seat is Wilmington. It is the most affluent of the three counties in the state of Delaware. In addition it is the smallest in area but largest in population.
On September 22, 1676, New Castle County was formally placed under the Duke of York's laws. It gained land from Upland County on November 12, 1678. Four years later, on June 21, 1680, St. Jones County was carved from New Castle County. It is known today as Kent County, Delaware.
On August 24, 1682, New Castle County, along with the rest of the surrounding land, was transferred from the Colony of New York to the possession of William Penn, who established the Colony of Delaware.
The city of Philadelphia, PA, as laid out by William Penn, comprised only that portion of the present city situated between South and Vine Streets and Delaware and Schuylkill Rivers. In fact, the city proper was that portion between High (Market) Street and Dock Creek.
Here is where the pioneers dug caves in the banks of the Delaware or built huts on the land higher up.
Native Americans were more or less present, either as spectators of the improvements then progressing, or, venders of their game and venison from the neighboring wilds. The Swedes and Dutch, who were the earliest settlers, as neighbors, brought their productions to market as a matter of course.
