William Marsh is my  6th  great-grandfather, through his first marriage to Sarah Webster.

William was born in Woodbridge, Middlesex Co., New Jersey on the  9 Dec 1734. William’s parents are Samuel and Mary Shotwell Marsh, Quakers in New Jersey. William married Sarah Horton on the 24 February 1780 in New Jersey. My best guess would be in Rahway, or Plainfield, New Jersey. The Quaker meeting at that time rotated between Rahway and Plainfield. http://www.plainfieldquakers.org/history/marriage.asp.
I have no more information on Sarah at this posting.

Happy 232 Anniversary!
