Names

[Nacheras]

Here am I again... :)

I think about agents (spy, diplomat, assasin), and could be you want to put surnames to them.

You can use the name+az or -ez about I´ve talking about yet. i.e Froilaz, Garces, Fernandez, Gonzalez, Ansurez, Sanchez, Velez, Vermudez, Ordoniez, Menendez, Ximenez or Jimenez, Nuniez, Munaz, Dieguez or Diaz...

In fact, I think that at IX century only the great nobles (magnates) used surname.

You can use the name of the birth town too. And then I provide you of a good list of towns to add as "of..." to the name:
Cangas, Pravia, Compostela, Valtierra, Gijon, Cosgaya, Tuy, Astorga (Asturica), Lugo (Lucus), Oporto, Braga, Chavez, Viseo, Simancas, Ledesma, Agueda, Salamanca, Zamora, Toro, Saldaña, Mabe, Amaya, Oca, Avila, Segovia, Sepúlveda, Clunica, Arganza, Osma, Miranda, Revenga, Cenicero, Carbonaria, Alesanco,Palencia, Valladolid, Sahagun, Santillana, Burgos, Lamego, Soria, Coca, Vitoria, Calahorra, Najera, Orense, Mieres.
