This answer will be expanded and clarified as I find more:
A familysearch tree has her parents as William Ditterline and Mary Bobst, and her paternal grandparents as Henry Ditterline and Elizabeth Houph. Working from that (but clearly needing more evidence), "History of Bucks County" page 13, mentions that Henry Ditterline married Elizabeth Houph, daughter of Joseph Houph, who was a son of Joseph and Elizabeth West Hough. I'd recommend reading that whole passage here (page 12-13):

...since you can track back several generations even further. Richard Hough, father of Joseph Hough (who married Elizabeth West), for example.
It appears this Joseph Houph (Hough) already has a wikitree profile https://www.wikitree.com/wiki/Hough-906 and it notes in the biography they Joseph Hough and Mary Tompkins Hough had daughter Elizabeth who married Henry Ditterline. Note this still doesn't prove Henry had William as issue and that they had Elizabeth, but we'll get there...
So now we have multiple sources saying that Joseph Hough married Elizabeth West, had a Joseph Hough, who had an Elizabeth, who married Henry Ditterline.
Next up, let's find some evidence that Elizabeth Hough (Houph) and Henry Ditterline had a son William. To get things started, I took the liberty of creating profiles of Henry Ditterline and Elizabeth Hough Ditterline.
Before I continue, is this the information you are interested in?
