Meaning & Origin
Gretl is a girl's baby name of German origin, a German diminutive of Greta or Margarethe (from Latin Margarita, meaning 'pearl'). The name is widely recognized through the character Gretl von Trapp in The Sound of Music — the youngest of the seven children in the famous Austrian family.
With fewer than ten recorded U.S. births, Gretl is a rare and warmly musical name — compact and charming, with the cheerful energy of Alpine folk tradition and Hollywood song built right in.
