This may be way off the mark but much further back than the 1800`s it seems some Spanish sailors , who were shipwrecked after their ships , which were part of the Spanish Armada ,ran aground in Tobermoray Bay and the Spaniards settled there . I wonder if anything like that happened in Ireland, Spanish sailors shipwrecked on the Irish coast.
Just a slight possibility. Best of luck.
