Many genealogists have Luis Lopez Ramirez and Sebastian Lopez Ramirez as brothers because Jaime Holcombe incorrectly stated in his cartas that they were brothers. They have even put this false information on wikitree and stated that it was a fact. These two men are related through marriage, but they aren't brothers. I won’t go into how they are related by marriage here in order to not confuse the issue as my intent here is to show that they aren't brothers.
Luis Lopez Ramirez is the son of Luis Lopez and Isabel Sanchez. This Luis Lopez Ramirez is married to Catalina Rubio, daughter of Pedro Hernandez and Maria Rubio.
Sebastian Lopez Ramirez aka Sebastian Ramirez is the son of Andres Lopez and Isabel Ramirez, and Sebastian’s wife, Ana de la Cueva aka Ana de la Cueva y Sandoval, is the daughter of Pedro Garcia de la Cueva and Maria Teresa Sandoval (Pedro is the son of Alonso Hernandez de Rebollar and Maria Hernandez de la Cueva).
Andres is the son of Alvaro Lopez and Catalina Lopez.
Alvaro Lopez is the son of Sancho (Sanchu) Lopez and Beatriz Gonzalez, and his wife Catalina is the daughter of Juan Lopez and Ines Lopez.
The credit for researching these families, and finding the correct genealogies, goes to my cousin Jorge Barba Gomez. I don't know if Jorge remembers me as the last time that i visited my Tio Pepe Barba Rubio’s home was about thirty-six years ago. On that last visit introduced my wife to my uncle and he shared that he was related to my wife through their Barba ancestry. I am more closely related to my tio Pepe Barba Rubio (famous Doctor) through his paternal grandmother, who is my great great grandmother.
