I found some info on the Bucks, Co Pitners. I have an Anna Pitner (b. 3/13/1791 Bucks Co, d. 6/18/1858 Wheeling, WV) married to a William Penn Charnock. I can't seem to find this Anna anywhere. I came across the following though.
John Pitner (Son of Hendry) and Jemima Davis
Sarah May b. 5/17/1787 d. 9/9/1809 yellow fever
James Neely b. 9/22/1788 d. abt 1842
Deborah b. 6/19/1790 d. 4/5/1879
Mary b. 5/30/1792 d. ?
Anna b. 1/11/1794 d. 12/14/1836
John b. 10/19/1806 d. 10/15/1823

This information and more is available on Google books, in "History of Bucks Co, PA" by William Watts Hart. It was published in 1905. Google gives you full access to this one.
