My father's parents came from Cork - Ryans and Dunleas from Lisgoold and Foleys and Mahonys from Rathcormac, both near Fermoy. Most of my Dad's first cousins are in Fermoy yet. My granduncle, Con Ryan, namesake of my father and I, came to the US as it seemed a better choice than having a price on one's head.
My mother's parents emigrated from Donegal and I have cousins both there and in Derry still, as well as my sister, brother-in-law, nieces and nephews (my brother-in-law is from Derry, they met there, and after a few years here emigrated back).
