Xavier, of Latin origin, is derived from the Basque 'Etcheber' meaning 'new house'. It gained prominence through Saint Francis Xavier, a co-founder of the Society of Jesus (Jesuits), who introduced Catholicism to India and Japan in the 16th century. The name was subsequently popularized among Christians and has been used widely across Europe and beyond.
The name Xavier experienced a notable increase in popularity between the late 1980s and early 2000s, with a peak of 62 births in 2007. Since then, its usage has declined significantly, reaching a low of 9 births in 2020.
