What is santas name in Poland?

Official name for Santa in Poland is Święty Mikołaj (St. Nicholas). However, in my region - Wielkopolska in Western Poland - he is called Gwiazdor. So, the rest of Poland gets presents from Św. Mikołaj twice (on Dec. 6 - mainly sweets - as it's his namesday, and on Dec. 24, as it's Xmas Eve, but here we get presents from Św. Mikołaj on the 6 and from Gwiazdor on the 24).
In some parts of southern Poland Xmas presents are not brought by Św. Mikołaj or Gwiazdor at all, but by Angel (Aniołek) or the Little Jesus (Dzieciątko Jezus).
