History & Origin
Caster is an English surname, connected both to an occupational term and to the many -caster place names from the Latin castra, 'camp'; it also chimes with Castor, the mortal twin of Pollux in Greek myth. Used as a first name it stayed very rare, appearing in the 1950s and peaking around 1953.
It was never common, given to only a couple dozen boys a year at its height, so a Caster from that time would be in his seventies today. It reads as a period surname-name rather than a rising choice, though its crisp sound fits the modern taste for occupational names.
