I may not be able to help in what you are working on, but our paths may cross.I am researching my Wensel/Weeter roots.You will have to excuse me, i am new to this and don't know the lingo.
Picking up from you:
O43. David Witter b. 1832 Toby Township, Clarion County d. 1907 m. Florence Catherine Weiser b. 1832 New Haven, Pennsylvania d. 1902
They had a son, Lorenzo Dow Weeter b. 1861 d. 1924 m. Ida Bell Hepler b. 12/12/1868 Porter Twp., PA d. 1899
They also had a bunch more (World Family Tree #1235) I traced Ida Bell Hepler though the "Descendants of Michael Hepler"
Lorenzo and Ida Bell had a daughter, Florence Cornelia Weeter, Who married Irad J Wensel, My great, great Grandfather.
If anyhting i am doing would be an interest to you i will gladly send more.I am in the process of compiling everything in Family Tree Maker.If you have any more info pre-David Weeter, I would appreciate it.
I remember as a Child, going to Cooks Forest for the Weeter-Wensel Family reunions.
