Last Name Tirandaz

What is the origin of the last name Tirandaz?

The surname Tirandaz is believed to have originated from the Basque region in Spain and northern regions of Portugal. It's one of several Basque-derived surnames that are often difficult to trace due to the complex system of traditional Basque naming conventions and the lack of written records before the late Middle Ages. The name Tirandaz may have been derived from a Basque given name, Tiurandi or similar variations, which is composed of the elements tiura (young bull) andhandi (lively). However, these connections are based on linguistic analysis and patterns in naming traditions rather than direct historical records. It's always a good idea to consult with a professional genealogist for more specific information about a particular family line.
