Long ago in the south, fireworks were the norm for Xmas, Cherokees, too.
Merry Christmas: Ulihelisdi danistayohihv ᎤᎵᎮᎵᏍᏗ ᏓᏂᏍᏔᏲᎯᎲ (they are happy/thankful they go shooting—as in firecrackers)
Santa claus: Distayohi ᏗᏍᏔᏲᎯ (he shoots- as in firecrackers, AKA firecracker man) He gives good children gifts: aneha didanedi nigada diniyotli osda ᎠᏁᎭ ᏗᏓᏁᏗ ᏂᎦᏓ ᏗᏂᏲᏟ ᎣᏍᏓ (he-gives gifts children good)

Merry Christmas!!!
Merry Christmas to you!
