Tilmo

Tilmo was an Irish missionary around 690, a former soldier who became a monk and then a preacher. He was one of the twelve monks who went to preach to the Frisians under Willibrord and Suidbert. He was given responsibility for the people of Cologne, built a chapel on an island in the Rhine and began to preach the Gospel; within a few years other Irishmen joined him, such as Wiro, Plechelm and Otger. The chapel became the monastery of Saint Martin in Cologne.
