I'm a pre-boom Jennifer, born in 1959, named after my mom's college roommate because she liked the name. My dad would have named me Debbie. I was Jenny until leaving for college, strictly Jennifer after that and now seem to be drifting into jen. I grew up as a solo Jennifer but in the late 80s I started having more experiences where I would be one of several Jennifers at an event. When I went to graduate school in 1988, I taught freshman (so they would have been born around 1970) and there were four Jennifers in my Design 1 class. I thought then about changing my name to Lee (my middle name) and considered it again recently when I changed my last name from my married name back to my birth name but so far I've stayed Jennifer--
I have heard the Love Story explanation and although I distinctly remember reading Love Story stealthily in algebra in high school. I didn't remember that being the main characters name until I heard the myth.
I'm planning to send her a nametag...
