Professional Genealogist Specializing in Mexican & South Texas Family History
Moises Garza is a professional genealogist, author, researcher, and speaker with more than 25 years of experience researching families from Mexico and the United States. His primary areas of expertise include Nuevo León, Tamaulipas, Coahuila, South Texas, and the families whose histories connect these regions.
Since beginning his genealogical research in 1998, Moises has dedicated much of his work to discovering, documenting, and preserving the histories of Mexican and Mexican-American families.
His research goes beyond simply locating names and dates. He focuses on finding original records, analyzing evidence, identifying relationships, resolving conflicting information, and building documented family histories supported by reliable historical sources.
More Than 25 Years of Genealogy Research
Genealogical research can become especially challenging when records cross borders, jurisdictions, languages, and centuries.
Through decades of research, Moises has developed extensive experience working with records from Mexico and the United States, particularly those relating to Northeastern Mexico and South Texas.
His research regularly involves:
- Catholic parish registers
- Mexican civil registration
- Marriage investigations and dispensations
- Census records
- Probate and estate records
- Land and property records
- Historical manuscripts
- Archival collections
- Military and government records
- Published genealogies and historical works
- Spanish colonial records
- Online and digitized archival collections
Whenever possible, conclusions are based on original or reliable historical sources rather than simply repeating information found in online family trees.
Specializing in Northeastern Mexico & South Texas
One of Moises's principal areas of expertise is the interconnected population of Nuevo León, Tamaulipas, Coahuila, and South Texas.
Families in this region frequently moved between communities that today lie on opposite sides of the United States-Mexico border. Successfully researching these families often requires understanding historical jurisdictions, settlement patterns, naming customs, Catholic records, Spanish-language documents, and the relationships among families that lived throughout the region.
Moises has spent decades studying these families and the records they left behind.
This specialized knowledge is particularly valuable when researching families associated with communities such as Monterrey, Saltillo, Cerralvo, Cadereyta, Linares, Camargo, Mier, Revilla, Reynosa, Laredo, San Antonio, and other settlements throughout Northeastern Mexico and South Texas.
Solving Difficult Genealogy Problems
Many clients contact Moises after reaching a point where they no longer know where to search.
Sometimes an ancestor seems to disappear from the records. In other cases, an online family tree identifies parents without providing evidence. A marriage record may be missing, an ancestor's birthplace may be uncertain, or several people with the same name may make it difficult to determine which person belongs to the family.
These are the types of problems that make professional genealogical research especially valuable.
Moises approaches these questions by developing a focused research objective, searching appropriate sources, comparing evidence from multiple records, studying relatives and associates when necessary, and documenting both discoveries and remaining uncertainties.
The goal is not simply to find an answer.
The goal is to find the evidence that supports the answer.
Author & Publisher of Genealogical Research
Research and preservation have always gone hand in hand in Moises's work.
He has authored and published more than 70 books and publications dealing with genealogy, family history, historical records, and the families of Northeastern Mexico and South Texas.
These publications reflect years of collecting, organizing, analyzing, and preserving genealogical information so that it can remain available to future generations of researchers.
His books and publications also form part of a broader effort to make difficult-to-find information about Mexican and Mexican-American families more accessible.
Building Resources for the Genealogy Community
In addition to conducting research, Moises has created and developed several genealogy projects designed to help others discover their family history.
He is the founder and creator of genealogy resources and communities including We Are Cousins, Mexican Genealogy, Las Villas del Norte, and Last Names of Nuevo León.
Through these projects, he has shared genealogical research, historical information, educational presentations, books, research strategies, and resources with researchers interested in Mexican and Mexican-American family history.
His work reflects a long-term commitment not only to researching individual families but also to improving access to information that can help the broader genealogy community.
Genealogy Speaker & Educator
Moises has also presented on genealogy, historical research, and Mexican-American family history for genealogical societies, conferences, and organizations.
His presentations focus on practical research methods, historical sources, genealogy resources, and strategies researchers can use to overcome difficult family-history problems.
Teaching genealogy has also strengthened his own research philosophy: researchers should understand where information comes from, how reliable it is, and whether the available evidence actually supports a genealogical conclusion.
Professional Research You Can Document
Family history is filled with stories, traditions, assumptions, and information copied from one family tree to another.
Some of it is correct.
Some of it is not.
For that reason, Moises places particular importance on documenting genealogical conclusions with sources whenever the surviving records make that possible.
Clients receive more than a collection of names and dates. Research is analyzed and presented so that clients can understand what was discovered, where the information came from, what the evidence suggests, and what questions may still remain unanswered.
That distinction is especially important for families who want research they can confidently preserve and pass on to future generations.
