Early life thumb|upright|Pope Adrian VI's birthplace in Utrecht Adriaan Florensz was born on 2 March 1459 in the city of Utrecht, which was then the capital of the Prince-Bishopric of Utrecht, a part of the Burgundian Netherlands in the Holy Roman Empire. He was born into modest circumstances as the son of Florens Boeyensz, also born in Utrecht, and his wife Geertruid. He had three older brothers, Jan, Cornelius, and Claes.Rodocanachi, p. 301. Adrian consistently signed with Adrianus Florentii or Adrianus de Traiecto ("Adrian of Utrecht") in later life, suggesting that his family did not yet have a surname but used patronymics only.Jos Martens, Bio and review of Verweij book at Histoforum Magazine.
