TYN meaning in Regional ?

Tyndall (the original spelling, also Tyndale, "Tindol", Tyndal, Tindoll, Tindall, Tindal, Tindale, Tindle, Tindell, Tindill, and Tindel) is the name of an English family taken from the land they held as tenants in chief of the Kings of England and Scotland in the 11th, 12th and 13th centuries: Tynedale, or the valley of the Tyne, in Northumberland. With origins in the ancient Anglo Saxon nobility of Northumbria, the Royal Scottish House of Dunkeld and the Anglo-Norman nobility, they have contributed courtiers, judges, writers, historians, sailors, airmen, scientists and philosophers to the history of England, Ireland and the new world. Two members of the family were offered, and declined, the throne of Bohemia in the 15th century and one of their number, William Tyndale, was the first modern translator of the Bible into English and one of the most important figures in the evolution of the modern language. The family is spread today throughout the British Isles and the English speaking world.
