That's a cool website Marcus. Here's my stats:
* There are 607,803 people in the U.S. with the first name Stephanie.
* Statistically the 82nd most popular first name.
* There are 0 people in the U.S. with the last name Pfenninger.
* This name is not found in our database, this means the name is relatively uncommon.
My hubby is probably related to every other Pfenninger in the US.
