From results so far, SNP Z214 clusters mostly in Iberia. It is the parent SNP of M153 the Basque marker, so this doesn't seem surprising.
The two exceptions seem to be a French origin, Trinquier, who is from Tarerach which is Eastern Pyrennees near the border of Cataluña and a non-Iberian(?) named Corden which is suspiciously similar to Cordón a Spanish name.
