Oswald of Northumbria
Ségéne also established the first Gaelic missionaries amongst the English, sending Corman and then Áedan, the latter of whom, with the help of King Oswald of Northumbria (who himself had spent time in exile at Iona), established a daughter house and bishopric at Lindisfarne. It is not known if Ségéne ever met Columba, but he was a vital collector/transmitter of stories about the saint.
