The name Gregor is a boy's name of Greek, Norwegian origin meaning "vigilant, a watchman". Gregor and is often added to lists like British Boy Names and discussed in our forums with posts like ""Don't call me ___, I go by ___"".
From the experts:
Two prominent literary namesakes make Gregor a somewhat risky choice. On the highbrow side, there's Gregor Samsa, the Kafka character who woke up one day to find himself turned into a cockroach. And then there's Gregor Clegane, one of the most feared and purely evil characters in the world of Game of Thrones.
It's a shame, because this earlier form of Gregory, quite common in Scotland, would otherwise make an attractive choice.
