Anson has always been rare, though you might think of actor Anson Williams, best known for playing Potsie Weber on 1970s sitcom Happy Days. As a direct result of the show's popularity, Anson charted in the US Top 1000 from 1976 to 1981.
Now a new generation of parents is discovering this English surname name. Anson could substitute for fading favorites like Alan and Austin. The name reentered the US Top 1000 in 2013 after a long absence and currently sits at Number 803.
