CASTILLO Family History

Recorded in the spellings of Castilla, Castillo, Castela, Castille, Castiglioni, Castiglione, Castillion, etc., this is a locational or regional surname which derives from the former independent kingdom of Castille, now a province within Spain. Curiously the name was originally French, the name deriving from the pre 10th century Provencal 'castel' (a castel) and vieil, meaning old, the old castle. 'Castille' was an area which was under continuous occupation from the time of the Romans who held it for three centuries, down through the Vizigoths, the Franks and later the Moors.
