This name derives from the Ancient Germanic “Bertulf”, composed of two elements: “*berhtaz” (light, bright, clear, shining one) plus “*-wulfaz” (wolf). In turn, the name means “shining and valiant wolf”. 1) Saint Bertulf was born in either Pannonia (Hungary) or Germany; he died in Artois in 705. He became a monk later in his life and founded a Benedictine abbey at Renty. Saint Bertulf († 639) was a German who converted to Christianity. He was the son of a pagan nobleman and was a near relative of Arnulf of Metz, whose example had such an influence on Bertulf that he became a Christian and in 620 entered the monastery of Luxeuil.
