Hello, Ardith,Welcome to Just Answer and thanks for your question. The answer to your question depends on which Myers/Myars family you are asking about. Myars is just a variation in spelling. The name was found in England going back to the 13th century as Myers, Miers, Myres derived from an old Norse word. Of course it was fairly common in its various spellings in Germany as well. The Latin word major is one source for the name.
