From the experts:
Long common in Europe, the elegant and regal Juliana, also spelled with two n's, has invaded these shores, in tandem with the more classic Julia. There were several early Saint Julianas and Queen Juliana was the long-reigning monarch of The Netherlands. Julianna Margulies has given that spelling of the name a substantial push.
Juliana has been on the Top 1000 since 1881.
