Xavier is of Spanish and French origin, translating to 'new house'. It's derived from the Latin word 'casarius', which means 'of the house'. Historically, it was often given to a child born in a new house or at Christmas time due to its association with St. Francis Xavier, a founder of the Society of Jesus (Jesuits) and a prominent figure in the Catholic Church during the 16th century. The name has also been used by royals, such as King Felipe VI of Spain whose full name is Felipe Juan Pablo Alfonso de Todos los Santos de Borbón y Grecia, with Xavier being his given middle name.
Xaviour was given to five babies born in 2013.
