Welcome to the forum, Michael

. A bit confusing indeed. in Ramiro Larrañaga's work he extends this smiths name to ANDRÉS MARTINEZ DE GARRATE. He and his brother Gabriel (36) are sons of ZABALA. It could be that their father was JUAN MARTINEZ DE GARATA, ZABALA (46). We could consider that he is called
el viejo (elder) by Palomares, to help distinguish him from JUAN MARTINEZ el mozo (younger) (42) in the table by their age, but not because they were familly.
Note that this is not 100% exact. It is known that the Palomares nomina contains a few inconsistencies. One thing we know as certain is that of JUAN MARTINEZ, that was active at an early stage, as listed in Lhermite's work (end XVI century), whose marks he describes are
precisely the ones shown nowadays out there. Yet in Palomares nomina we can find not right name neither his full marks, which i suspect is listed in the table as JUAN MARTIN (39).
Confusing indeed
