King Dom Pedro I, the eighth king of Portugal, governed from 1357 to 1367, during ten years. He was the son of King Dom Afonso IV and Dona Brites and was born in Coimbra on April 8th, 1320 and died on the same city on January 18th 1367, with only 47 years old. He was nicknamed “the Just” or “the Cruel”. He married Dona Constância from Castille and they had a son called Dom Fernando who became king after him.  However  King Dom Pedro I is more famous because of his mistress Dona Inês de Castro. Due to  a political conspiracy his father King Afonso IV permitted   a group of three conspirators to cut the neck of  this  unfortunate lady. Dom Pedro went after the killers and was able to get two of them and made sure that their hearts were removed alive!

The love affairs of King Dom Pedro I

When Dom Pedro was young he had a love affair with a lady from Lisbon by the name Teresa Lourenço, daughter of Lourenço Martins, a business man from Lisbon , and she gave birth to a boy. Dom Pedro asked Lourenço Martins, the grandfather, to protect the king’s bastard son, who was given the name João, to educate him and make him a chevalier. It was this bastard son of King Dom Pedro I, who later became the famous King João I.    He was born in Lisbon on August 14, 1356, acclaimed king on April 6, 1385, and died in Lisbon on August 14, 1433, the same day we completed 77 years of life. He won the famous Battle of Aljubarrota against Spain on August 14, 1385.

 

The love affairs of King João I

Even before he became King, João I had love affairs with a lady from  Alentejo called Inês Pires, daughter of Barbarão and she gave birth to a boy who was named Afonso. King João I governed Portugal for 48 years initiating the famous Dynasty of Avis.

King João I  protected this bastard son, even legitimized him as his son  before he became king. King João I also name this Afonso Count of Barcelos, and  arranged his marriage  with  Beatriz Pereira Alvim, the daughter of Nuno Álvares Pereira (Hero of the Aljubarrota Battle), who was the largest land owner in country at that time, and gave them the title of Dukes of the House of Bragança.

I am given these  detailed explanations of  these illegal  love affairs for us to understand  that the Y chromosome of King Dom Pedro I, was passed on to his bastard son who later became King João I and the Y chromosome of this king was passed on to Dom Afonso who became the First Duke of the House of Bragança.

Now we should exam the sequence of all the males in the Dynasty of Avis, and also all the males of the Dynasty of the House of Bragança. 

       The male sequence of the Dynasty of Avis

King João I married Dona Filipa de Lencaster of the House of England and they had the following sons, and they all had the same Y chromosome.

 

Dom  Duarte  who became the next King

Dom  Henrique – Prince Henry who became the Administrator of  the Order of Christ.

Dom Fernando –  who became the Master of the Order of Avis

Dom  João –  who became the Master of the Order of Santiago  

Dom  Pedro – Duke  of  Coimbra and  Reagent 

 

King Dom Duarte had the following sons:

Dom Afonso V  who became king after him.

Dom  Fernando –  who became the First Duke of Beja. This Duke of Beja is  ACCUSED  of getting pregnant a young lady from  the Royal Court by the name Isabel Gonsalves Zarco, daughter of João Gonsalves Zarco,  the famous discover of the  Island of Porto Santo (1418) and the Island of Madeira (1419).

Of this love affair between Fernando and Isabel, was born a boy to whom was given the name Salvador Fernandes Zarco who later changed his name to Cristóvão Colon, known  today as Christopher Columbus.

 

This First Duke of Beja married Dona Beatriz and they had the following sons:

Dom  Manuel who became king by the  name of Dom Manuel I.

Dom João -   Second Duke of Beja  and Duke of Viseu

Dom Diogo –  Third Duke of Beja and Duke of Viseu   

 

Equally all other males of the Dynasty of Avis, such as King João II, and King João III all possessed the same Y chromosome

We should recall again that Dom Fernando, First Duke of Beja – the  ACCUSED  -- was a biological brother of King Dom Manuel I.  

And if the Y chromosomes NEVER change in various generations, ALL the descendents of King João I had to possess the same Y chromosome which started with King Dom Pedro I.

  Now let us analyze the male sequence of the House of Bragança, who have the same Y chromosome as the Dynasty of Avis.


The tomb of the First Duke of the House of in the Church of São Francisco in the City of Bragança.  

First Duke of Bragança – Dom Afonso I  

Second Duke – Dom  Fernando

Third  – Dom  Fernando II

Fourth  – Dom Jaime

Fifth  – Dom  Teodósio

Sixth  - Dom João I

Seventh  – Dom Teodósio II

Eighth – Dom  João  after became King  Dom  João IV

Nineth  -  Dom Teodósio

Tenth  – Dom Afonso VI,  Became King  

Eleventh  – Dom  João  V,  Became King

Twelfth – Dom José I, became King

Thirteenth – Rainha Dona  Maria I.

This Queen married her uncle Dom Pedro II, who was the brother of  King Dom José and they had one son who became  the fourteenth Duke of Bragança  with the name of Dom Jose Francisco Xavier.

Fifteenth – Dom João VI became King

Sixteenth – Dom Pedro IV became King

Seventeenth – Dom Miguel I became King

Eighteenth – Dona Maria II married her uncle Dom Miguel, but they had no children.  In her second  marriage,   she married Dom Fernando of Saxe-Coburgo –Gotta House and they had a son called Dom Pedro. With this marriage the Y chromosome typical of the House  of Bragança was LOST!   How did the House of Bragança RESTORE  its own  Y chromosome?

Nineteenth -  Dom  Pedro V, became king  

Twentieth  – Dom  Carlos I, became King  

Twenty first  – Dom Luís Filipe de Bragança

Twenty second  – Dom  Miguel de Bragança (Miguel II ), son of  Dom  Miguel I and  of   Adelaide de Loewenstein- Wertheim-Rochefort-Rosenberg.  With this Duke  the Y chromosome typical of the House of Bragança  WAS  RESTORED  in the genetic sequence of the males.   

Twenty third  – Dom  Duarte Nuno de Bragança, grandson of  de Dom  Miguel I and son of Dom  Miguel of Bragança also called Dom  Miguel II.  

Twenty fourth  – Dom   Duarte Pio,  who is alive and lives in Sintra, and is  the candidate to become the next King of Portugal .

 

Therefore, if the Y chromosome NEVER changes,   the male Dukes of the House  of Bragança as described above,  must have all the same  Y chromosome including the actual Dom Duarte Pio.  

The tombs of all the males of the Dynasty of Avis and of the House of Bragança have been  all localized for the Professor Francisco Corte Real and his scientific team to start their investigations of DNA  in the old bones, so they later can  make the comparative analysis with Y chromosome in the direct descendents of Cristóvão Colon  in Spain.

In the next article we will show the genetic sequence of the Dukes of Verágua who are all descendents of the Don Diogo Colon Moniz,  (in Spain the last name is the mother’s) who became  the first Duke of Verágua, in Madrid, Spain and who was the legitimate son of Cristóvão Colon and Beatriz Moniz, of the Island of Porto Santo,  in the archipelago of Madeira, Portugal.

If our historical analysis is correct, the Dukes of Verágua must have the same Y chromosome as the males of the Dynasty of Avis, of the House of Bragança and of King Dom  Pedro I of Portugal  

If the ACCUSED,  Dom Fernando, First Duke of Beja,  was indeed the biological father of Christopher Columbus or Cristóvão Colon or Salvador Fernandes Zarco, it is for Professor Corte Real and his  scientific team  to make the DNA diagnosis  which will become  the undeniable historical proof!   Only with the unique method of the DNA can the real proof  be demonstrated scientifically.

 In the following article we will describe: The  Dynasty of the Dukes of Verágua.
