Wulfram was born in the diocese of Meaux, at Mauraliacus, an insecurely identified place near Fontainebleau, probably Milly-la-Forêt, Essonne.

[4] 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, Wulfram converted the son of King Radbod and was allowed to preach.

[3] The custom was that people, including children, were sacrificed to the local gods having been selected by a form of lottery.

Wulfram 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.

The faith of the missionaries (and their power to work miracles) frightened and awed the people, who were baptized and turned away from paganism.

In one, Wulfram is credited with the miraculous delivery of a stillborn baby, the mother having commenced labor on 20 January (the feast day of Saint Sebastian).

A week after Easter, prayers to Wulfram caused her belly to split open so the dead child could be delivered, after which the wound healed as if it had never been, leaving only a "token of the cut".

In the other, Wulfram is credited with the safe passage of an accidentally swallowed clothespin, which left the body of a two-year-old boy after three days without having injured it: "Is it not miraculous how through all the twists of the boy's intestines, as if through fine small round tubes, the copper sharp object, now going up high, now going down low, could travel without getting stuck anywhere or causing wounds, and so at last through Nature's lower parts find a way out all in one piece?

"[7] After the building at Crowland was damaged by fire, there was no longer a suitable place for keeping the relic, so it went to Grantham for safe-keeping.
