Love What We Do

Unlocking Your Ancestry brings a passion for research to each and every project that we work on, from the identification of a single historic document (such as a birth certificate or a military record) to the creation of a complete family tree.

Our specialties are in Latin American, Basque, Spanish, UK, and Americas genealogy, we have worked on genealogical projects for families in the United States shedding light on their linkages to the Old World and early arrivals to the Americas.

Robert Mark Minguillon is the Founder of Unlocking Your Ancestry, and our team of professional Genealogists are all committed to finding your ancestors, building out your family tree and providing you with a sense of history.

Our Story

On his father’s side, the family, with the exception of a few notables (like the painter Francisco Goya) came from humble beginnings. They were hard working laborers, farmers and sheep herders and mostly from small towns in the Aragon and Navarre provinces of Spain.

On his mother’s side, he is a descendent of Alfonso II, King of Aragon, and through him, to much of the European royalty throughout the 900s, 1000s and 1100s as well as to Diego Lopez de Haro V, the founder of Bilbao, Spain.

Robert Mark became interested in his family’s genealogy at the early age when he was asked to assist his uncle in researching, documenting and building his maternal family tree.

He and his team are members of Association of Professional Genealogists, Genealogical Society of Hispanic Americas, and National Genealogical Society.

What People Are Saying

Mark’s “Ancestors of Diego Lopez V de Haro – Lord of Vizcaya” is a genealogic masterpiece the likes of which I have not found in any library or archive. I am fortunate to have a copy of in my library. The printed opus is contained in four three-inch ring binders!

In the ten years that took me to chronicle my family’s genealogy, I benefited from Mark’s counsel and advice and clear thinking. His dedication to ensure that facts, names, places and dates were completely accurate made it possible for me to write a book about my family’s thousand-year old history that will stand the test of time.

Mark is the right person to help you search for your ancestors, learn where you came from and leave a legacy for your grandchildren.

We have been so excited reading through our genealogic report and getting to know our ancestors.

Thank you for doing such a thorough investigation. All the details that you took the time to put into our genealogical report have turned our reading into a delightful treasure hunt of our family tree.

To be able to give my children this level of understanding about where they came from is invaluable.

Wow! Working with Mark was amazing. He created the perfect gift for my wife and her sisters. I was able to share the limited information I had regarding my wife's parents and grandparents and Mark was able to research her family back to the 1500's in Wales. Mark was very communicative, sharing exciting finds during his research. Mark's research was the hit of the holiday. He created a frameable printed family tree as well as a personalized binder for my wife and her sisters with 6 additional binders of supporting research. Mark exceeded the depth and scope I expected for this project. Thank you for the hours of work spent to introduce my wife to her ancestors. We would highly suggest you hire Mark for your ancestry project.
