Many of the Saints mentioned above have strong links to Devon going back over a thousand years. Many are linked to strange and miraculous tales, and most are still venerated or celebrated each year on the days above.
We also suggest the Devon Flag be flown at local events such as the Dartmouth Regatta, The Hunting of the Earl of Rhone in Combe Martin etc, whenever Devon's Rugby team are playing and the day after each win.
