Ni hao Xiao-xian ,
The following is a list of alphabetical spanish names, their significance and origin
http://www.behindthename.com/nmc/spa.php

Some name in particular ?
Next list some examples:
* Andrés: a generous person :-P (its my name ... )
* Tonatiuh: the god of sun or light (aztec culture)

Significative ? (ups), maybe the religious context is the most used, for example:
* Maria (or Mayra), the mother of Jesús
* Pedro, the apostol
* Jesús, ehmm the son of god
* Andrés (je, one again ..), another apostol

I hope this will be useful,
Andrés

if you want laughing, moreover, go to : http://usuarios.lycos.es/vengavaleno/curioso/018.htm There are real names.

Claudia = crippled person (Roman Latin)
Gonzalo = Lord of War (Spanish from Germanic)

BTW , I don't like wars :-)
