Arturo,

You have to follow all the leads in search of the answers you are
looking for.  One quick observation regarding your message:  Aranzazu
is most definitely a Basque surname and while everything is possible,
the Basque population is predominatly R1b, with just a mere 2.1%
belonging to E3b, so this is something to consider.
