Jocelyn has gotten new life and popularity as a result of the current passion for lyn endings. Though it was a male name in medieval times, now Jocelyn couldn't sound more softly feminine. Jocelyn was in the Top 100 from 2002 to 2013, and now sits just outside it at 133.
John Galsworthy's 1989 novel Jocelyn is part of his Forsyte Saga. Singer Joss Stone's birth name was Jocelyn.
Jocelyn would make a pretty namesake name to honor a Grandma Joyce.
