Two key things to consider.

So say, if your name was John Doe, in Spanish folks could respectfully call you Don John or Señor Doe. Either is fine. (If you're a lady, then it's doña/señora). I use those naming things now and then, it felt right for the setting. The fun thing is, the font I used didn't have a letter ñ. So I had to steal the line on the ñ from another font and photoshop it in by hand every time like a maniac.
