Julianna

With the addition of one letter, Julianna is a new name and a respelling of the more-familiar Juliana. For a while in the 1960s, changing “–ana” to “–anna” was a thing: For example, Adriana could also be spelled Adrianna, and Briana could morph into Brianna. Since the double-n Julianna came into existence in 1965, it lagged behind its big sis, giving baby ample opportunity to see this name to the top. Julianna Margulies, who was on The Good Wife for seven seasons, is maybe the best-known bearer of the name.
