The spelling makes the tradition Non even more of a non-name.

The legendary St. Non was the mother of St. David, the patron saint of Wales. David was raised in a convent by his mother and went on to become a great teacher and bishop. Non is also known as Nonna and Nonita, and is associated with Cornwall and Brittany along with Wales. While the name Non is well-used in Wales, it is largely unknown in the US and maybe be heard as the negative word "none" or prefix "non".
