- We have added a new article discussing the origins of the Seminario surname and an interesting new DNA clue that may shed some light on the family's ancestry and nobility.

3/25/2019 -
We found the baptismal record of Juan Pizarro Yupanqui, the last son of the conquistador Francisco Pizarro and his Inca consort, Cuxirimay Occlo Yupanqui, named Angelina by the Spaniards.  The record is dated May 22, 1541, just a month before Pizarro was assassinated on June 26, 1541.  It is a find worth mentioning because some historians do not even recognize the existence of this child, who the Pizarro family of Loja, Ecuador believe was their ancestor, but some historical records say died at age 4. The record was found in the microfilms of, film number 8109158, image 56 of 275.  This microfilm is of the first book of baptismal records maintained by the Catholic Church of Lima, Peru, which later became the Cathedral of Lima.  Our thanks to the Instituto Peruano de Investigaciones Genealógicas, who reported the discovery of this book of baptisms on their website.

5/7/2018 - About three months ago we located church records for Piura on microfilm.  Today we added a guide to finding these documents.  The documents we have found on microfilm changed our perceptions of Agueda Seminario Besada, a somewhat mysterious figure in Seminario genealogy.  While she lived after 1800 and would normally be outside the scope of this site, we decided to share our findings about Agueda.

9/4/2017 - We obtained a copy of the original letter of December 2, 1544 written by Hernando Pizarro to Gonzalo Pizarro about the fate of Francisco Pizarro's children, and updated the chronology of the children.

9/2/2017 - We received a partial transcription of the will of Julio Cesáreo Seminario y Gonzaga and updated the article on Seminario ancestry.

3/5/2017 - In November 2016 we researched the possibility that Clara Castro Manrique de Lara and her daughter Leonor Manrique de Lara, residents of Piura in the 16th century, were descended from the noble Manrique de Lara family of Spain.  We failed to establish the connection.  Recently, in our Pizarros of Antiquity tree, we found Catalina Manrique de Lara, who married a Pizarro ancestor in the early 14th century.  When we researched further, we found a completely documented connection to the noble Manrique de Lara family in the encyclopedia of the García Carraffa brothers.  In addition, we discovered that the Manrique de Laras were descended from the same Gothic kings as the Pizarros.  We added these new findings to our Manrique de Lara report, and we prepared a Catalina Manrique de Lara tree to document the connection to the Spanish nobles and Gothic kings.  Unfortunately, the Seminarios and other descendants of the Pizarros of Loja cannot claim this ancestry with certainty until we can resolve the enigma of Juan Pizarro.

3/3/2017 - We found a letter written by Gonzalo Pizarro in 1547 in which he describes "PizarrodelaRualoe" as a kinsman.  We believe this letter refers to Alonso Pizarro de la Rúa, a soldier born in Trujillo, Spain who accompanied Francisco and Gonzalo Pizarro in the conquest of Perú, and later became a royal land grant holder and a municipal administrator in Trujillo, Perú.  The historical records of those times often referred to Alonso only by his surnames run together, "PizarrodelaRua".  This lettter, along with other recently discovered documents that identify "PizarrodelaRua" and Julián de la Rúa as brothers born in Trujillo, Spain, are a great help in analyzing the possibility that these brothers were relatives of our mysterious ancestors Juan Pizarro of Loja, his wife María de la Rúa, and their daughter Isabel Pizarro de la Rúa.  Julián became a royal land grant holder in the ancient province of Calvas, Ecuador, near Loja, around 1573.  Born in 1514, he was old enough to have been the father of María de la Rúa, who must have been born between 1540 and 1550.  He had other children during these years.  Perhaps the baptism of María de la Rúa was not recorded or not digitized, but at least these clues encourage us to search in the Calvas churches for the marriage certificate of Juan Pizarro and María de la Rúa, and for the baptismal certificate of Isabel Pizarro de la Rúa.

2/22/2017 - As part of our continuing effort to identify the Juan Pizarro who lived in Loja between 1561 and 1581, we conducted a chronological study of the children of Francisco Pizarro, and wrote a report on the study.

2/5/2017 - We added 84 Seminario ancestors to our site, extending the tree of the Pizarro family from the 14th century back to the 5th, and linking several kings of León, Castile, Galicia and Asturias.  The extension of the Pizarro lineage is presented in two segments:  Tree1 and Tree2.  We also added a report on our investigation into the ancient Pizarro ancestors.

12/30/2016 - We just found proof that Ygnacia Calderón Dávila, wife of Martín Seminario Gandino, was a descendant of a noble family of Castille.  We added the Calderón family to our Nobility page, created a tree for them, and wrote a report on the status of our research.
12/22/2016 - Today we removed the blog from our website and replaced it with the Articles section.  It became necessary to do this because we were flooded by ads in the form of comments.  We promised not to allow advertising on our site, but erasing around 100 ads a day proved to be time consuming.  Any questions, comments or suggestions related to the subject of this site, or any contributions of information or documents, may be directed to  We will publish these unless your questions or comments are meant to be private.

11/19/2016 - Continuing our effort to identify the Juan Pizarro who lived in Loja, Ecuador and was the ancestor of the Pizarros of Loja, the Seminarios and other related families, we have researched two recently discovered Juan Pizarros born around 1540:  Juan Pizarro Cermeño y Juan Pizarro Inquill.  Neither seems to be our Juan Pizarro of Loja.  About Pizarro Cermeño we are fairly sure.   We are less certain about Pizarro Inquill because there is no evidence or record of his death.  We set up new records in our database, and updated our report on the Pizarro/Yupanqui research with our conclusions. 

11/11/2016 - We finally finished the report on the Manrique de Lara research.

10/22/2016 - Good news!  Google has digitized the 80 volumes of the magnificent Enciclopedia Heráldica y Genealógica Hispano-americana published by the García Carraffa brothers in 1919, plus 5 additional volumes added by later researchers.   Now students of Spanish and Latin American genealogy can research online rather than having to travel to the handful of libraries that have the complete set.  We have modified the Sources page with links and instructions for using this new resource.

10/10/2016 - Added a new introduction to the article Pizarro/Yupanqui - Status of the Research to tell the story of the ancient Pizarro and Hinojosa noble families.

9/19/2016 - Completed a major revision of the article Pizarro/Yupanqui - Status of the Research to incorporate new evidence from Dr. Oswaldo Páez Barrera.  The claims of the Pizarro family of Loja, Ecuador to have descended from Francisco Pizarro and Cuxirimay "Angelina" Yupanqui are presented and examined.  Detailed information for some of newly added records is included.

9/19/2016  -  Added new records to the website database for the following people.  They have not been confirmed as ancestors, but they may be.   The records were set up to keep documents and notes as we continue our research.
