At least 70% Irish, maybe 50% famine-emigrant Galway Irish. The rest is older Irish-American, Ulster Scots, and English. So far as I know, my heritage isn't too interesting - lots of hobos, poor people, horse/car thieves, etc. - though my Grandpa Moore started a toy company and my Granddad Furey was in the navy, we're all proper nowadays
My relatives have pictures of saints tacked to their wall, and rosaries hanging in their cars and such, and my dad always takes us out to eat on his saint's day. They eat what's probably best described as "soul food" and sing ALL THE TIME. Surnames include Moore, Sullivan, and Furey. But we've never been stereotypical "Irish-Americans" in the popular sense. I've never worn a stupid hat on St. Patrick's Day, or eaten corned beef. I just know a lot of songs, and music, and history and fairy tales - like the selkie story, which I assumed when I was little was as well-known as Cinderella
I like that in the Irish worldview, the sacred and the mundane are often intertwined. A seal can be a woman, and a woman can be a saint - the world is a wondrous place.
Ive heard of the selkie before, I love Irish music and folklore and its so kool that you still keep in tact with your irish heritage, i wish our family was but were not all that much, in fact theres a selkie song
