wilfrid, deposed from his archdiocese of york, exiled from northumbria and on his way to rome to seek papal support, landed in frisia in 678. and was warmly received by aldegisel, who entertained him for several months over the winter, probably at utrecht. according to stephen of ripon, wilfrid's biographer, aldegisel encouraged wilfrid in his effective evangelism and "[the frisians] accepted his [wilfrid's] teaching and with a few exceptions all the chiefs were baptised by him in the name of the lord, as well as many thousands of common people." it is possible that aldegisel was one of the early converts. however, it has been doubted whether wilfrid was actually successful in frisia, since there is no other evidence of the success of christianity there before the work of willibrord.
