English form of the Latin name Valentinus, a derivative of valens ‘healthy, strong’. This was the name of a Roman martyr of the 3rd century, whose feast is celebrated on 14 February. This was the date of a pagan fertility festival marking the first stirrings of spring, which has survived in an attenuated form under the patronage of the saint.
Spanish: habitational name from any of several places named Villar(r)eal, from Spanish villa ‘(outlying) farmstead’, ‘(dependent) settlement’ + real ‘royal’ (Latin regalis), as for example Villarreal de San Carlos in Cáceres. The places were so named from having some particular connection with the Crown.
