My Great-great-grandfather Andrew was born in Ireland in 1840, died in the US.
I’m guessing he came to the New World before his tenth birthday.
Which is a different sort of problem ~ but I think Irish independence solved that part.
The famine refugees were more likely from Germany and Scandinavia ~ which doesn't mean they weren't really Irish but they probably weren't.
Here's a recipe handed down. Take some meat ~ if you have meat. Chop it up. Chop a potato into slices. Put in a pan. Bring it to a boil. Wait until the slices are transluscent ~ about 2 or 3 minutes. Toss in the meat. Stir. Wait until brown or gray.
Serve hot. Feeds a small family.
No meat? Slice the potato thinner.
