This one stumped me for a long time, but I think I’ve finally figured it out.
The word-name Dart debuted in the U.S. baby name data in the mid-1950s and hung around for several years before disappearing again:
1960: 6 baby boys named Dart
1959: 5 baby boys named Dart
1958: 8 baby boys named Dart
1957: 10 baby boys named Dart
1956: 12 baby boys named Dart [debut]
At first I got stuck on a pair of auto-Darts: the Chrysler Dart, a concept car that was in the news briefly in mid-1956, and the Dodge Dart, a production car that went on sale in 1960. Neither one was a good answer.
Finally I happened to find a 1955 film called Foxfire that featured a main character named Jonathan “Dart” Dartland (played by Jeff Chandler). He was a half-Apache mining engineer whose new marriage to socialite wife Amanda (played by Jane Russell) was threatened by the cultural gap between them.
The screenplay, based on a 1950 novel of the same name by Anya Seton, was written by Ketti Frings.
What do you think of “Dart” as a baby name?
P.S. Foxfire was the film playing aboard the SS Andrea Doria the moment it was struck by the MS Stockholm.
Please note that I did include names in the gray area between one syllable and two syllables. The deciding factor on these particular names (such as Charles, Miles, and Noel) will be your own interpretation/accent, so be sure to test the names out loud before making any final decisions.
