Qvartus

The name Qvartus is a rare variant of Quartus, which directly derives from the Latin word 'quartus' meaning 'fourth'. In ancient Rome, names indicating birth order were common, especially for children born after the first three. Quartus would have been given to the fourth-born child in a family. While not a common praenomen (given name), it was used as a cognomen (surname) or occasionally as a personal name.

Its usage has remained extremely rare throughout history, largely confined to specific historical or literary contexts where a direct reference to 'fourth' was intended. The 'Qv-' spelling is an even rarer, perhaps archaic or idiosyncratic, variation of the more standard 'Qu-'. It does not appear to have gained significant traction in any particular culture or era.
