Since there’s no letter Q in Ukrainian, today is a wildcard day. I decided to do German names because part of Ukraine was controlled by the Austrian Habsburgs during the 19th and early 20th centuries, and some upper-class Ukrainians became very Germanized. Thus, there’s a plausible connection between Ukrainian and German names.
Female names:
Quieta is a rare name which comes from the Latin word quietus (quiet). This was the name of a saint.
Quilene is a rare name, probably a combination of names starting with Qui- (e.g., Quirina) and names ending with -lene (e.g., Marlene, Helene). It might also be a short form of Aquilene, a form of Aquilina (eagle).
Quirinia is a rare feminine form of Roman cognomen Quirinius, of unknown etymology. This isn’t to be confused with the very similar name Quirinus, which possibly means “spear.”
Male names:
Quintian is a rare form of the Roman cognomen Quintianus (originally Quinctianus), which ultimately derives from Quintus (fifth). This name was traditionally given to a fifth-born child.
Quiriakus is a German form of the Greek name Kyriakos (of the lord).
Quirin is the German form of Latin name Quirinus, which may derive from the Sabine word quiris (spear). I love all forms of this unusual name!
