From the experts:
The Greek name of sixteen popes and fifteen saints, the gregarious Gregory became big in the United States with the emergence of admirable actor Gregory Peck (born Eldred) in the late 1940s. From 1950 to 1973, it was in the Top 30, with nickname Greg becoming a Cool Dude name. So while Gregory may have morphed into an Upstanding Dad Name, it carries the winning combination of deep roots and a modern feel that still deserves consideration. In addition to Gregory Peck, there have been dancer-actor Gregory Hines, racer Greg Lemond, golfer Greg Norman, and musician Gregg Allman. Gregory Goyle is a Harry Potter wizard.
