Zámbó came from a minor Transdanubian noble family which belonged to the kindred Pápa.
In August 1384, Zámbó, along with Nicholas Szécsi and the House of Lackfi, renounced allegiance to Queen Elizabeth, who ruled in her daughter's name as regent, due to her intention to break Mary's engagement to Sigismund of Luxembourg and have her married to Louis of France [REF].
