... It may be remembered that St. Ursula was said to be Cornish; and that her only recorded companion should bear a Cymric name, is in favour of some shade of foundation for her story.  Kordula is in consequence a German name...
... An old myth of the little bear and the stars seems to have been turned into the legend of Cologne, of Ursula, the Breton maiden who, on her way to her betrothed British husband, was shipwrecked on the German coast, and slain by Attila, King of the Huns, with 11,000 virgin companions.  Some say that the whole 11,000 rose out of the V. M. for virgin martyr; others give her one companion, named Undecimilla (q.v.), and suppose that this was translated into the 11,000.  Skulls and bones, apparently from an old cemetery, are shown at Cologne, and their princess's name has been followed by various ladies.
