Gage, part of the craze for one-syllable surnames, had been in the Top 250 for more than two decades until it finally dropped out last year, with associations to tasty green gage plums and the mathematical gauge.
Gage was first noticed as a character in Stephen King's Pet Semetary--though Gage Creed was far from an admirable role model. That book was published in 1983, and the movie came out in 1989, the very year that Gage hit the Top 1000. It is now at Number 281, down more than 100 places in the last five years.
Gage has spawned a couple of successful spelling variations, so don't be surprised to run into a Gaige or a Gauge.
