A Latin document of Diocese of Wrocław called Liber fundationis episcopatus Vratislaviensis from around 1305 lists Gorki villa vlodari thus mentioning what is now Górki Wielkie for the first time. However, it was written in an atypical form and suggests that a village was much older. The reason why it was inscribed to the document was connected to a process of extracting of a part of the village, which belonged wholly to dukes, to form a new village given to a knight. The part which remained in dukes hand was later called Górki Małe, while a knight's part Górki Wielkie. As so a village of Górki (Małe) functioned probably before 1290, when the Duchy of Teschen was formed (where both belonged ever since). From it was extracted a knights' villages which was then first mentioned in Liber fundationis... Explicitely it was later mentioned as [from] malych Gurek in 1566.
