Mary Mae Woodring was possibly the wife of Christian Rees, but there remains much to research on this. Records from Philipsburg or Bellefonte are good candidates for more information.
Mary Zeller Rees was the wife of John Rees, both of Philadelphia. Records from the First Reformed Church in Philadelphia show that Mary Zeller's middle name was Magdalene, and that she was born on July 21, 1780. That would have made her 22 when she married John Rees, 43, born on August 15, 1758.
Mary Zeller's parents are listed as Philip and Margaretha Zeller of Philadelphia. The Reformed church records indicate that they were married on June 4, 1769, and that her mother's maiden name was Ries. Mary had two brothers, William and Daniel. Mary Zeller was baptized in this church. John and Mary's marriage is included in the church records: "1802, May 23, Rees, Joh, and Mary Zeller." This entry is probably how Christian Rees was confused with John Rees, but early records such as the Trenton prisoner list and the list of Philipsburg settlers do not refer to him as "John" (or "John Christian").
In 1872, Mary Zeller Rees was living in Philadelphia. From an address on Coates Street, she signed an application for a veteran's pension by making an "X" between her first and last name. The pension cites various locations where her husband served some 85 years before during the Revolutionary War. The supporting letters note that she was in need, and she may have been in a hospital. She died on August 17, 1872, and was buried in the Laurel Hill Cemetery, in the same plot as John Rees.The Old Reformed Church building still exists and is located in old town Philadelphia.
The following is an interesting quote from the timeline history of the Old Reformed Church (from their web site):
1777 - "Pastor Casper Weyberg was thrown into prison for his preaching and converting the Hessian mercenaries to the American cause."The Old Reformed Church of Philadelphia, has an interesting history of its own. Read more of the church's history at its web site.But it doesn't seem like Christian Rees ever attended that church after his capture at Trenton.
