Elizabeth is one of the most popular girls' names of all time, the female equivalent of James or William. Yet Elizabeth has so much going for it—rich history, broad appeal, and timeless style—that no matter how many little girls are named Lizzie, Eliza, and Beth, you can still make Elizabeth your own.

Like Greta, Gretchen is a German Margaret diminutive that has become an American quasi-classic, though not much used today, having dropped off the list in 2009. She was at her high point in the 1970s, making it into the top 200.

Adeline in all its forms, including Adelyn, is rocketing up the list, but we do prefer the original to the variations. Or you might consider varying it yet further to Adelia, Adele, or Adelaide. Or lengthen it to Madeline/Madelyn.
