This is Lisle, pronounced "LEEsull", and named after the character "Liesl" in The Sound of Music. Sadly, I did not look up the correct spelling when I named her.

Liesl von Trapp was played by Charmian Carr. Her website is charmiancarr.com. Charmian Carr is pretty, yes, but is not quite as exotic as her namesake, born 43 years after Liesl sang Sixteen Going on Seventeen.
