Susanna Diehl, My Great-Great Grandmother (Updated)

Here's a genealogy post. We've known for a while that my great-great grandmother on my father's side was Susanna Diehl (spelled various ways) of Pennsylvania. She was married to David Rothenberger on 26 September 1867 in Allentown, Pennsylvania. By 1880, the family is in Clinton county, Indiana (according to the 1880 US Census). Susanna dies later that year at the age of 31, leaving behind four children: Peter J. Rothenberger (12 years old), Sallie V. Rothenberger (8), Olville O. Rothenberger (6, and my great grandfather), and Anna A. Rothenberger (2). The names are from the census, and are in some cases known to be incorrect. Anyway...

We never really could find out anything about her family. At some point I managed to find her father as Joseph Diehl, in Lehigh county, Pennsylvania (1860 US Census). Well, tonight I had a breakthrough, and found the entire family in the 1850 US Census. In Upper Milford Township, Lehigh county, Pennsylvania, we have Joseph Dehle, 38, a shoemaker owning real estate valued at $400; his wife, Heaster (or Harter) Dehle (37); children Jacobe Dehle (11), Maria (8), Daniel (5), Rebaca (5), Julean (3), and Susana (0). This particular area was enumerated on 25 September 1850, so that fits in well with Susanna's birth in late 1849-early 1850. The radical changes in name spelling made it difficult for me to track this down before. If I can figure out how, I'll post an image of the Census page.

Now, to track down more information about this part of the family.

Update: As promised, here's the interesting part of the Census image:
