Yep...Spanish were there assimalating people and giving them "Christian" names almost 200 years earlier.
Being a native of Beaumont, I can say with almost certainty that these are probably illegal aliens. There were very few Hispanics in Beaumont prior to the current invasion of the last twenty years are so.
The ones there before had been in Beaumont since the late 1800s and early 1900s and were well assimilated by the 1960s - lots of intermarriage, etc. Many WWII vets.
