A martyr's cult carries the name across Europe
A name needs carriers, and Valerie found a powerful one in the church. Wikipedia credits St. Valerie of Limoges with having "probably exercised the greatest influence in spreading the name."
Her cult traveled the roads. Pilgrims practiced her veneration along the Camino de Santiago, the medieval Way of St James, helping push the name across the continent. Around 985, relics tied to her were moved to Chambon-sur-Voueize, anchoring her cult in the Limousin region of France.
