ARANZABAL

This surname is originally from Ubera, Guipuzcoa.

The meaning comes from "aranz" (a bush with thorns or a thorny bush) and "zabal" (which means wide). This could have several meanings. It might connotate a wide thorny bush or more likely a wide open space where there may have grown a thorny bush or bushes.

The arms are a field of blue, three gold towers arranged horizontally.
