Born in Northumberland; died c. 730. Plechelm was ordained a priest. He
went to Rome with another Northumbrian priest, Saint Wiro, and a deacon
named Otger. In Rome, Wiro and Plechelm were consecrated regionary
bishops. After doing missionary work in Northumbria, they went to the
Friesland area of the Netherlands, where they evangelized the
inhabitants of the lower Meuse Valley under Saint Willibrord or Saint
Swithbert, and built a church and cells at Odilienberg on land granted
to them by Blessed Pepin of Herstal. They were martyred while preaching
the Gospel
