- Knight of King Fernando of Portugal's Royal Council.
- One of the ambassadors sent by King Fernando to Enrique II of Castile, in Tuy at the time, to negotiate and clarify several difficult issues pertaining to the Treaty of Alcoutim (1371), including the exchange of castles taken by either side and the marriage of King Fernando to Enrique's daughter Leonor.
Affonso Dominguez
Is this the same person as Afonso Domingues Barateiro, treasurer of the gold sent to Aragon the year before (1370) as part of the negotiations with Pero IV to wage war on Enrique II of Castile?
Barateiro was described as "an honest Lisbon merchant".
