Ferdinand of Portugal, Lord of Eça

Ferdinand of Portugal, later de Eza or de Eça (English: Ferdinand) (1378 – Eza?) was the son of Portuguese Infant João, Duke of Valencia de Campos. João, was a son of king Peter I of Portugal with powerful and literary famous for several centuries in several European languages, Galician lady Inés de Castro, "the Queen who ruled after her death".
His father, Infante John, Duke of Valencia de Campos, (*Coimbra 1349 - +Salamanca 1397), buried there, had been legitimized as Infant of Portugal, and became Duque de Valencia de Campos in Castile through his marriage to one of the bastards of bastard king Henry II of Castile. Fernando's father John, had married in 1376, (1st marriage), Castilian lady Maria Tellez de Menezes, assassinated shortly after in 1378 by her 11 years junior in age husband, who had been alerted of her disloyalty, apparently.
Then, he married again in Valencia de Campos in 1378 Constanza de Castilla, señora de Valencia de Campos, illegitimate daughter of bastard King Enrique II of Castile, (1334 - king by assassination in 1369 of legitimate brother Pedro I of Castile - 1379), who was therefore the step mother of orphaned Fernando de Portugal. He became thus Consort duke of Valencia de Campos, in the former kingdom of León, by accepting one of the bastard daughters, named Constanza, of the new king (since 1369, aged 35, through assassination), the Royal bastard known as Henry II of Castile, probably poisoned by the king of Navarre in 1379, aged only around 44-45.
It must be stressed here, that the Black Death in Europe of around 1349 - 1350, seems to have modified in the whole of the European Continent after those times, all kinds of moral or sexual standards within Christianity, to say the least, both in men and women. We are threading also in the dynastic changes, working trades and working people shortages 1350 - 1450, which could be described as the "Century of the Bastards", everywhere in Europe, rather than the fashionable "Marxist" explanations on the rise of Capitalism, perhaps outdated for the 21st-century historians.

He was the 1st Lord of Eza, a place in Galicia, from where he took his surname, corrupted in Portuguese into Eça, and which was given to him by turbulent Enriquez family member and relative Fadrique de Castilla, 1st Duke of Arjona, deceased in prison.

It is said Fernando was married or perhaps lived with many wives, all of them alive. Other sources say he married six times, having three or four of them alive at once, but only the name of the sixth wife is known.

Apparently, this sixth one, was Isabel de Dávalos, daughter of Pedro López de Dávalos, Adelantado of Murcia, and granddaughter of Ruy López de Dávalos, Constable of Castile . By her he had:

All from different women, it is said that he had 42 children, between sons and daughters.

In the end of his life he repented, and he started wearing a rope of the Habit of Saint Francis of Assisi, with which he was buried and which appears in the Coat of Arms of his family in purple with the look of a carbuncule.
