Duchy of Cleves
Sycamber was born in Venray in upper Gelderland, close to the border with the Duchy of Cleves. In antiquity, this was the territory of the Germanic people called by the Romans the Sicambri, Sigambri, Sugambri, etc., and from this ethnonym he took his Latin surname. It can thus be surmised that he self-identified in some sense as "German."
