Catherine Bradley m. Henry Aurand

I have one Bradley in my family: Catherine Bradley, b. 4 May 1812, d. 25 Apr 1875 in Granville Twp, Mifflin Co, PA. She m. Henry Aurand 21 Oct 1832 in Lewisburg, Union Co, PA. I have been unable to identify her parents. I haven't found a Bradley bunch in Union County or its parent, Northumberland County. Anyone have a clue?
