Margot, a French pet form of Marguerite, has a lot going for it: spelled with or without the final 't', it's one of the few girls' names with the dynamic o-ending sound; it's familiar, yet uncommon enough to be distinctive. It's on the rise currently, gaining 114 spots between 2012 and 2013 to enter the Top 1000; it's 109 on Nameberry.
Movie buffs will remember Bette Davis's archetypal role as Margo Channing in All About Eve (the actress named her own daughter Margot), while balletomanes will associate the name with the great English dancer Margot Fonteyn (born Margaret).
In the film Margot at the Wedding, Margot was played by Nicole Kidman; in The Royal Tenenbaums, Gwyneth Paltrow was Margot T. Gorgeous Australian actress Margot Robbie has made an impact here in the film The Wolf of Wall Street. Trivia note: Margaux Hemingway was originally Margot, but changed the spelling to honor the wine from the French village of Margaux that was drunk by her parents on the night she was conceived.
