Basque orgin of the Mestayer surname?

According to Dad (Robert Mestayer), our bloodline comes from the Basque region between Spain and France. English is my native language, Spanish is familiar, French is foreign, but Basque is quite Alien to me! It's nearly Vulcan... Which leads me to believe we were ancestors of a visiting mother ship that landed in the mountain areas between Spain and France. Just a little joke.

I added the Basque interface for our site. Here is an informative log that accompanied the language pack:

Population 580,000 in Spain (1991 L. Trask U. of Sussex). There are 2,000,000 residents of the 3 provinces of Basque territory; 25% were born outside the territory, 40% in the territory were born to Basque parents. 4,400,000 in Spain have a Basque surname; 19% live in Basque country. Population total all countries 580,000 or more.
Region:: French-Spanish border, 3 Basque provinces: Alava (Araba), Biskaia (Biskay), and Gipuzkoa of the Autonomous Basque Community (CAV); in the northern area of the Autonomous Region of Navarra (Nafarroa) of north central Spain. Also spoken in Australia, Costa Rica, Mexico, Philippines, USA.
Alternate names VASCUENSE, EUSKERA
Dialects GUIPUZCOAN (GUIPUZCOANO, GIPUZKOAN), ALTO NAVARRO SEPTENTRIONAL (HIGH NAVARRESE, UPPER NAVARRAN), ALTO NAVARRO MERIDIONAL, BISCAYAN (VIZCAINO), AVALAN. Batua is based on Guipuzcoan, the central and most widely known dialect. A fair amount of inherent intelligibility among all regional varieties except Souletin. Regional varieties are sometimes preferred for oral use, but in Spain there is also a fairly strong desire for the Batua unified standard. Bilingualism in Castillian, Catalan sometimes. Ages 2 to 20 and over 50 as first language, all ages as first or second language in mainly Basque-speaking areas. Euzkadi is the name of the Basque region, not for the language.
