I think George is more likely to be English. But ofcourse anyone of any descent could be named George. I saw a query on this forum, I think, where a family of Portuguese descent changed thier name to George from Jorge, which as you probaly know means George in Spanish/Portuguese. Now if the name is spelled Georges that could be French I guess. You will just have to work backward, starting with current family members and where thier from in Mexico back to the town or village. Then continue looking for any written records. Census, deeds, marriage etc. The Catholic church (in the area your looking) may have Information. I have heard that they keep good records. Good luck.
