St Willibrord of York

I was a bit confused about whether Willibrord was Frisian and evangelised Yorkshire, or vice versa - but it seems he was from North Yorkshire. He has also been said to be "joyful of character and holy of life". I can think of a lot of people I've known who have been joyful, but not holy, and several who've been holy, but not joyful, but it is a real gift to be both.
