Ivor comes from the Welsh meaning "Tower of manhood" and Bangor is a small town on the coast of Gwynedd. The two together "Ivor" and "Bangor" were twinned about two hundred years ago when Bangor became a center for learning in Wales. A large population of middle class Gay men became the "Bangor Dandys" which was changed in the book 'How Green Is My Valley?' in the middle of the 20th century.
"He is the only Ivor Bangor in the village" or "I knew he was an Ivor Bangor by the way he walked" or "she was married first to an Ivor Bangor but that didnt last".
