I do remember the admissions department saying that "Ben" was the most popular name in my college class. I'm not quite sure why parents of our social-economic stratum decided why that name was so cool circa 30 years ago, but they did.

Of course, "David" seems to have been reasonably popular for the past 3,000 years. It never really became the number 1 name, but it seldom fell below the top 10 either.
