As described in historical dictionaries
Patronymica Britannica (1860)
ORANGE. A AVilliam de Orenge is a Domesday tenant in co. Bucks. AVhence this " William of Orange " came, I cannot guess ; certainly not, I should say, from the district from which his great namesake, some six hundred years later, originally had his title, that being a small town and ancient principality in the South of France, about twenty miles from Avignon, and formerly a dependency of Holland.
