don’t think it’s Irish i thought Catholic. In Spain after Halloween they have the day of the dead. Families go visit their dead relatives and have picnics at the cemetery. Then a big fiesta on the night.
Don't a few countries have a day off the dead thing? I'm thinking S.American countries, so your Spanish theory could be correct.
Mexico do . https://en.wikipedia.org/wiki/Day_of_the_Dead https://mymodernmet.com/skeleton-sculptures-day-of-the-dead/ https://www.independent.co.uk/life-...respect-appropriation-halloween-a9179661.html
I thought it was Scottish, at least the direct ancestor of American style Halloween. I know the Pumpkin carving is (although they used Turnips) and begging people for stuff seems a very Scottish thing to do.
