The Armada thing is a canard. We know quite a lot
about Armada wrecks off Ireland and have accounts
of survivors. they number in the 100s at best &
are thus genetically insignificant. The dark-eyed
round-headed etc. folks found in Ireland are
undoubtedly the indigenous stone-age people who
built, e.g. newgrange.
Eamonn DeValera was born in Brooklyn & his father
was contemporarily Spanish.
