Question: What age was Zapolya's son when Vrancic and Isabella Jagiellon moved to Transylvania?

In 1541 he moved with her to Transylvania, but he mostly traveled fulfilling diplomatic services because of his disagreement with cardinal Juraj Utjesinovic's policy of claiming the Hungarian throne for Isabella's and Zapolya's infant son (instead of conceding it to Ferdinand I as per Treaty of Nagyvarad).
