Willibrord (c. 658 – 7 November AD 739) was a Northumbrian missionary saint, known as the "Apostle to the Frisians" in the modern Netherlands. He became the first Bishop of Utrecht and died at Echternach, Luxembourg. His father, named Wilgils or Hilgis, was styled by Alcuin as a Saxon of Northumbria. Newly converted to Christianity, Wilgils entrusted his son as an oblate to the Abbey of Ripon, and withdrew from the world, constructing a small oratory, near the mouth of the Humber, dedicated to Saint Andrew. The king and nobles of the district endowed him with estates until he was at last able to build a church, over which Alcuin afterwards ruled. Willibrord grew up under the influence of Saint Wilfrid, Bishop of York. Later he joined the Benedictines. He spent the years between the ages of 20 and 32 in the Abbey of Rath Melsigi, in County Carlow, Ireland, which was a center of European learning in the 7th century.
During this time he studied under Saint Egbert, who sent him and eleven companions to Christianise the pagan Frisians of the North Sea coast at the request of Pepin of Herstal, Austrasian mayor of the palace, who had nominal suzerainty over that region. Willibrord travelled to Rome twice. Willibrord was not on the usual pilgrimage to the graves of the apostles Peter and Paul and the martyrs. Rather "he made haste to Rome, where Pope Sergius then presided over the apostolic see, that he might undertake the desired work of preaching the Gospel to the Gentiles, with his license and blessing". As such he came to the pope not as a pilgrim but specifically as a missionary. The second time he went to Rome, on 21 November 695, in the Church of Santa Cecilia in Trastevere, Pope Sergius I gave him a pallium and consecrated him as bishop of the Frisians. He returned to Frisia to preach and establish churches, among them a monastery at Utrecht, where he built his cathedral. Willibrord is counted the first Bishop of Utrecht.
In 698 he established the Abbey of Echternach on the site of a Roman villa in Echternach, which was donated to him by Pepin's mother-in-law, Irmina of Oeren, the wife of seneschal and Count Palatine Hugobert. After Hugobert died, Irmina founded a Benedictine convent at Horren in Trier. When a plague threatened her community, she gained the help of Willibrord; and when the pestilence passed by the convent, she gave Willibrord the lands for his abbey in Echternach.
Pepin of Heristal died in 714. In 716 the pagan Radbod, king of the Frisians, retook possession of Frisia, burning churches and killing many missionaries. Willibrord and his monks were forced to flee. After the death of Radbod in 719, Willibrord returned to resume his work, under the protection of Charles Martel. Winfrid, better known as Boniface, joined Willibrord and stayed for three years, before travelling on to preach in Frankish territory. St. Willibrord is remembered on November 7.
