Alfons of Braganza (* 1377 ; † 1461 ) was the illegitimate son of John I from his relationship with Inês Pires . He was excluded from the line of succession because of his descent (his marital half-brother Edward I succeeded his father to the throne), but he was highly regarded at court and king.
In 1401 he married Beatriz Pereira de Alvim , heir to the war hero Nuno Álvares Pereira , whose wealth he could dispose of. Peter of Portugal made him Duke of Braganza in 1442 .
This originally illegitimate sideline was repeatedly married to the Avis family in the following generations .
The daughter Isabella comes from Alfons marriage , who married her uncle Johann, a younger legitimate son Johann I and became the grandmother of Isabella of Castile .
