This name derives from Latin "dŏmĭnus > dŏmĭnĭcus", meaning “head, sovereign, lord, patron, organizer”, (title given to the emperors after Augustus). It has been used since the fourth century with the Christian meaning of "holy to the Lord", although later its use was extended to children born on a Sunday (the day consecrated by the Lord). The name is still used, mostly by Catholics. The use of the English version began in the XIII century, in honor of St Dominic. Domingo Félix de Guzmán (English: Saint Dominic, Spanish: Santo Domingo, 1170–1221), was the founder of the Dominican Order. Dominic is the patron saint of astronomers. Saint Dominic is honored in Roman Catholic Church, Anglican Church and Lutheran Church.
