I had read, heard, or seen most of these while a child in the 70s-80s:

Dr. Seuss, How the Grinch Stole Christmas! (1957) book
“The Witch in Pursuit,” A Christmas Adventure in Disneyland (1958) LP
Pearl S. Buck, Christmas Ghost (1960) book
Bobby “Boris” Pickett, “Monster’s Holiday” (1962) LP
Astrid Lindgren, The Tomten (1960) book
How the Grinch Stole Christmas! (1966) TV movie
Jane Thayer, Gus Was a Christmas Ghost (1969) book
Norman Bridwell, The Witch's Christmas (1970) book
Linda Glovach, The Little Witch’s Christmas Book (1974) book
Robert Bright, Georgie’s Christmas Carol (1975) book
Tomie DePaola, The Cat on the Dovrefell: A Christmas Tale (1979) book
Casper's First Christmas (TV Movie 1979)
James Flora, Grandpa's Witched-Up Christmas (1982) book

Possibly that had fueled an interest in Christmas ghost stories, although at the time I wasn't aware that the terms like "ghost stories" and "goblin tales" had for centuries been catch-alls, somewhat equivalent to "weird tales." For those interested specifically in stories involving disembodied spirits of the dead or wraiths of the living who are soon to be dead, that can be confounding, admittedly.

S. T. Joshi in The Weird Tale (1990) had written "I find the term 'ghost story' particularly irksome, although it has gained wide usage. To me 'ghost story' can mean nothing but a story with a ghost in it; but others have thought differently." I get that. That said, think of both Charles Dickens and M. R. James. The Ghosts of Christmas Past, Present, and Yet to Come are not spirits of deceased people like Marley and the other misers Scrooge saw, and in other stories like "The Story of the Goblins Who Stole a Sexton" have goblins taking the supernatural role. "The Ash-tree" by James, adapted by the BBC as part of A Ghost Story for Christmas, involves witchcraft and venomous spiders; look for ghost, wraith, phantom, spirit, etc. in it: you won't find them.

One does need to explain that, though, I'd noted in the introduction to the Valancourt Book of Victorian Christmas Ghost Stories volume four that the tradition was rooted in bugbears and bogies of all sorts. The subtitle of 1730's Round About Our Coal-Fire: or Christmas Entertainments had listed "Stories of Fairies, Ghosts, Hobgoblins, Witches, Bull-Beggars, Rawheads and Bloody-Bones." In volume five, I'd noted that lexicographer Francis Gross wrote in 1787 that “ghosts, fairies and witches, with bloody murders, committed by tinkers, formed a principal part of rural conversation, in all large assemblies, and particularly those in the Christmas holy-days, during the burning of the yule-block.” Some people don't read introductions, unfortunately! Oh, well.

I never have found any bloody, murderous tinker stories, but perhaps those only existed as an oral tradition and never made it to print. That said, Christmastime stories of murderous psychopaths without any supernatural elements were common enough in the Victorian era in print, and continue on today in Christmas horror movies like Black Christmas (1974).

With Christmas horror movies too, the releases stacked up, ready to be viewed on the sly by Gen Xers as children or rented by themselves when older. Silent Night, Bloody Night (1972), Christmas Evil (1980), To All a Goodnight (1980), Don't Open Till Christmas (1984), Silent Night, Deadly Night (1984).

Also true with respect to print anthologies, the first published of which I'm aware being Manley and Gogo Lewis' Christmas Ghosts: An Anthology (1978), followed by Peter Haining's Christmas Spirits: Ghost Stories Of The Festive Season (1983).
