Will have to read that when I get time today. Growing up I went to parochial school and Saint Nicholas was the patron saint of the church & school.
Granted it's been decades since I've even thought about it, but I don't recall any mention of Turkey. IIRC, he was Greek and we should be right around his holy day, where we would have to put our shoes in the hallway and "gifts" would be left in them - usually an orange and some other items to teach the story of him providing gifts to orphanages.
Ultimately the Turkey piece could be completely true, as the church would move remains around as needed to establish a foothold to sell their wares.
