when the Romans first came to Britain they saw these fair haired people

Close, but no seegar. The story was about some Pope who, upon receiving moral support or some such things said, of the Angles, "Not Angles, but angels." Works perfectly good in Latin, too, maybe even better than in English. I could look it up if someone who knows more doesn't beat me to it.

Otherwise, you've got it right, dxb.


Edit:

It was Pope Gregory, and it was in response to seeing some Angles for sale in a slave market. According to this site http://sspx.ca/Angelus/2000_December/St_Augustine_of_Canterbury.htm he wasn't Pope yet. The Latin is : Non Angli, sed angeli. I'm assuming the G was still hard in angeli.
