The city of Philadelphia dates back to October 27, 1682 when William Penn laid out plans to construct a magnificent city. Records available to genealogists stretch back to the seventeenth century when the city was first founded. The area grew very quickly, and by the time of the Revolutionary War it was the largest and most important city in the new world. Philadelphia was founded on the principles of religious tolerance, and played a vital role in the history of the United States as we gained our Independence.
