It is said} that when Saint Boniface withdrew from his missionary work in Friesland, in order to visit Rome for the second time, St. Wulfram stood in for him in Friesland.
However, Boniface was a younger contemporary, his first and abortive mission in Frisia began in 716 or so, probably after Wulfram had died.

Whatever the order of these events, in Frisia, St. Wulfram converted the son of King Radbod and was allowed to preach.
The custom was that people, including children, were sacrificed to the local gods having been selected by a form of lottery.
Wulfram, having remonstrated with Radbod on the subject, was told that the king was unable to change the custom but Wulfram was invited to save them if he could.
The saint then waded into the sea to save two children who had been tied to posts and left to drown as the tide rose.
According to the story, the turning point came with the rescue of a man, Ovon, who had been chosen by lot to be sacrificed by hanging.
Wulfram begged King Radbod to stop the killing, but the people were outraged at the sacrilege proposed.
In the end, they agreed that Wulfram's God could have a chance to save Ovon's life, and if he did, Wulfram and the God could have him.
Ovon was hanged, and left for a couple of hours, while Wulfram prayed.
When the Frisians decided to leave Ovon for dead, the rope broke, Ovon fell and was still alive.
Ovon became Wulfram's slave, his follower, a monk, and then a priest at Fontenelle Abbey.
The faith of the missionaries (and their power to work miracles) frightened and awed the people, who were baptized and turned away from paganism.

Even Radbod seemed ready for conversion, but just before his baptism, he asked where his ancestors were.
Wulfram told him that idolaters went to Hell.
Rather than be apart from his ancestors, he chose to stay as he was.
