The Spanish Armada landed in Galway. Do you think it possible someone of surname Moran settled in Ireland?
There are similar surnames in many places for example there is Morin which I believe is French. Perhaps the names in Ireland and in Spain are the same but unconnected and so completely coincidental and unrelated. There is also another Spanish surname Moron with an accent on the last "o".
Could it be a Norman French name in Ireland for it seems unusual.
