  Title: Welsh Tract
  Passage: The Welsh Tract, also called the Welsh Barony, was a portion of the U.S. state of Pennsylvania settled largely by Welsh-speaking Quakers.  It is located to the west of Philadelphia.  The original settlers, led by John Roberts, negotiated with William Penn in 1684 to constitute the Tract as a separate county whose local government would use the Welsh language.  The Barony was never formally created, but the many Welsh settlers gave their communities Welsh names that survive today.

  Title: List of mayors of Washington, D.C.
  Passage: The list of mayors of Washington, D.C. is a reflection of the changing structure of its local government.  Washington, D.C. was formed with the passage of the amended residency Act of 1791 and the government at the time defined in the 1790 Residency Act.  From 1791 to 1802 the District was managed by a three-member board of Commissioners.  With the passage of the 1802 Organic Act, the District was divided into two counties, Alexandria County west of the Potomac and Washington County to the east.  The counties were governed by levy courts made of providentially appointed Justices of the Peace, but the District's three cities, Georgetown, Washington City and Alexandria each had their own municipal government.  Prior to 1812, the levy courts had a number of members defined by the President, but after that Washington County had 7 members.  In 1846, Alexandria County returned to Virginia.  In 1848, the Washington County levy court was expanded to 11 members and in 1863 it was reduced by two to nine members.  With the District of Columbia Organic Act of 1871, the three municipalities within the District of Columbia were abolished in favor of a single District government, whose chief executive was a territorial Governor.  This office was abolished in 1874, and replaced with a temporary three-member Board of Commissioners appointed by the President.  The board was made permanent in 1878 and this system continued until 1967, when it was replaced by a single mayor-commissioner and city council appointed by the President.  Finally, in 1974, the District of Columbia Home Rule Act allowed for District residents to elect their own mayor.
