Unsual quirky names here enjoy ...

So uncool it's cool! Bertie makes for a boyish nickname for Alberta, Roberta, Bertille, Albertine... or just use it on its own, à la Billie or Frankie. Old school unisex nickname names are back in and Bertie has an undeniable vintage charm; particularly given soundalike Birdie rising in the ranks.

A distinctively Welsh name that's feeling more and more usable these days.
