Sure to be mispronounced.

A spunky diminutive of Hanne, itself derived from Johanna or Johanne.

Emphasizes a four-syllable pronunciation, rather than the traditional three of Giovanni.

A Scandinavian short form of Johanna, properly pronounced with a Y sound at the start, but would likely be read as the more prosaic "John-a" in an English-speaking context.

Short form of Yann, the Breton form of John.

Juana with an X factor.

Rare feminine form of Hans — a John derivative — occasionally heard in Germany and other German-speaking countries.

La is the French prefix used to indicate paternity, much the same way Mc or O' are used in Irish and the son suffix is used in English. First names with the La prefix were popularized in the 19th century by the Free Blacks of New Orleans, who used La plus the father's first name, making Lashawn (or LaShawn) a name meaning son (or child) of Shawn, a phonetic spelling of Sean, the Irish variation of John.

Variant (mis)spelling of Siobhan.

A romantic way to get to covetable nicknames Gia and Nina.

This common name for both boys and girls in Scandinavia would definitely work better as a feminine name in the U.S.

Currently fashionable in Slovenia.

Rather dated smoosh name.

A gorgeous Hebrew name that was originally used for boys, but is now increasingly used for girls as well. As a bonus, you get the sweet built-in nickname Nina.

A joyous, celebratory-sounding name.

Nyakyusa form of John.
