Names I really don't like...

Flavius is an ancient Roman family name associated with a dynasty of emperors. It has an appealingly flavorful first syllable, and is the name of a stylist in the Hunger Games series.

Xabier is a masculine Basque variant of the name Xavier, which originated from the Basque place name Etxeberria, meaning 'new house.' The name gained prominence through St. Francis Xavier, a 16th-century Spanish missionary and co-founder of the Jesuit order. The distinctive spelling with an 'X' reflects traditional Basque orthography, where the 'X' is pronounced similar to 'sh' or 'ch.' Xabier remains very popular in the Basque Country of northern Spain and southwestern France, where it celebrates Basque cultural heritage and language. Outside of Basque regions, this spelling is less common but offers an authentic alternative to the more widely used Xavier. The name combines cultural specificity with a rich historical background.
