Greetings Sue
You are right St Nicholas, was from southern Turkey, there are a couple of legends about him, the most common being that he was told of a man who could not get the money together to provide dowries for his three daughters. Because of the man was planning to send his daughters to work in a brothel. St Nicholas, a Christian bishop, saved them from this fate by throwing three bags of gold through their window one night. Hence the sack of presents at Christmas, with a lot of materialistic additions, country to country over the years.
