Guster is an unusual and unique given name, of French origin. It's derived from the French word 'guster', which means 'to taste'. This name could be chosen for its culinary associations or simply for its distinctive sound. There are no specific historical figures or characters associated with this name. In popular culture, it has been used sparingly, perhaps most notably in the band Guster, an American alternative rock group formed in 1991 at Harvard College. However, as a given name, it remains quite rare and unique.
"The name Guster had a notable surge between 1925 and 1929, with five births each year from 1925 to 1926, followed by a peak of seven births in 1929. However, it was not consistently popular throughout the decade, as seen with only five births in 1913."
