Thessalonike

If Thessaly, Thalassa, and Theano aren't bold enough for you, how about this striking choice? It was originally borne by an ancient Macedonian Greek Princess — the daughter of King Phillip II and a half-sister of Alexander the Great. She married the Macedonian ruler, Cassander, who named the city of Thessaloniki after her.

Comprised of the elements Thessalos ("Thessalian") and nike ("victory"), the princess was given the name to honor a battle victory of her father's in the region of Thessaly.

A very rare option, the modern Greek form, Thessaloniki, and the Latinized form, Thessalonica, are used just fractionally more often.

Pronounced thes-ah-LOH-nee-kee.
