Sewickley PM was held for 81 years. The MW was part of Providence PM from 1789 until 1826 when Sewickley PM was granted by Redstone QM. Although the meeting did not suffer a Hicksite or Gurneyite division, it was weakened by attrition as the nineteenth century progressed. A MM was held here from 1865 to 1874, and afterwards Sewickley PM was subordinate to Salem MM in Ohio until the meeting was laid down in 1907. |
