Another Jenn here... short for Jennifer... though my Dad used to call me ifer... he didn't want the otehr half of my name to get jealous because it was underused.... lol!
Lol. We had 5 in my 6th grade class. We had to have special names for all of them. One, whose last name also started with a J, ended up being called JJ. I think she had a pretty hard time ridding herself of that nickname after we got to Jr. High. Lol.
