Although I have only traced my family to N.L. Mexico, I have found two references for the origins of the Tamez name, that point to Arabic roots. 1. A Dictionary for Spanish Surnames in the S.W. U.S., by Richard D. Woods/Grace Alvarez-Altman. Tamez: Varient of the Arabic "Tamyiz" to sererate, distinguish, hair sieve or strainer, screen, sifter, flour-bolt. 2. From Orginal Spanish Names, "Como Te LLamas, Por Que Te LLamas Asi", by Richard Santos. Tamez: Arabic to seperate. He/She who seperates. From the Moors (700 A.D.) (Morarabic) to seperate. One must keep in mind that Spain was an Islamic state from 711 - 1492 c.e. Over that 700+ years of rule, the Muslims left an everlasting imprint on Spanish society and culture in the form of relgion, art, architecture, language, food, NAMES, etc. One can obtain additional information on this period in history @ www.gslis.utexas.edu/~astimac/spain.html Keep an open mind, things may not be as they appear.
