Research your ancestors on MyHeritage

Understand the HistoryUnderstand the History

For insights into New Mexico’s early history, look into Spanish land records, Spanish census documents, and Mexican databases—particularly when tracing ancestors between 1536 and 1848. During that period, the territory fell under foreign governance, so adopt an international perspective in your research. Be aware that both Spain and Mexico conducted colonial censuses from roughly 1750–1830, as well as in 1823 and 1845, although surviving records are incomplete.

Familiarize Yourself with Major Historical Periods: New Mexico’s heritage is shaped by centuries of Indigenous settlement, Spanish colonization (starting in the late 16th century), Mexican governance (1821–1848), and U.S. territorial rule (1850–1912), before finally attaining statehood in 1912.
Consult Key Historical Works: Read recognized histories of New Mexico to learn about Spanish land grants, Indigenous settlements, and the impact of westward expansion. Understanding broad historical themes will help you interpret the records you uncover.
Identify Cultural Influences: Spanish naming conventions, Indigenous traditions, and the role of Catholic missions can all affect naming patterns, record-keeping styles, and the availability of documents.

Understand the Geography and JurisdictionUnderstand the Geography and Jurisdiction

Study a Modern Map: Begin with a current map of New Mexico to see the layout of cities, towns, and counties.
Compare with Historic Maps: Jurisdictional boundaries and county lines have changed significantly. Compare older maps with current ones to track a family’s potential record trail.
Focus on Population Centers: Records are often more centralized in larger towns or historically significant mission sites.

State BoundariesState Boundaries

Check Historical Timelines: From 1848 to 1912, New Mexico was a U.S. territory. Before that, it was part of the Spanish Empire and later Mexico. Knowledge of political changes helps determine where archival sources might be found (e.g., Mexico City archives, Spanish records, or U.S. federal records).
Use Boundary Change Resources: Tools such as the Atlas of Historical County Boundaries (available online) or specialized genealogical reference books often show the evolution of state borders.

County BoundariesCounty Boundaries

Review County Formation Dates: Check when each county was formed—many shifted lines over time. For instance, some land that was once part of Taos County might later have been reassigned to Rio Arriba County.
Seek County Histories: County historical societies or local genealogical groups often have compiled materials detailing boundary changes and key events.
Consult County Seat Information: Knowing the county seat is crucial because that is typically where courthouses and record archives (land deeds, probate, and court records) are housed.

MigrationMigration

Trace Spanish Colonial and Mission Routes: During colonial times, settlers followed mission trails and trade routes (like El Camino Real de Tierra Adentro) linking Mexico to New Mexico.
Study 19th-Century and Early 20th-Century Migration Patterns: Homesteaders, miners, railroad workers, and ranchers moved into New Mexico. Look for references to these occupations in census and land records.
Check Family Bibles and Oral Histories: Migratory paths often surface in personal documents—recorded recollections or letters referencing travel, new territories, or distant relatives.

Vital Records – Birth, Death, and MarriageVital Records – Birth, Death, and Marriage

When you can’t locate a couple’s marriage record in their home county (or even in New Mexico), you might find it in nearby cities with more lenient regulations, such as Las Vegas, Nevada, or Yuma, Arizona—the region’s equivalent of “Gretna Greens.” Couples who were underage or who needed to bypass other restrictions frequently traveled to these locations to wed.

Start with State Vital Records: Official statewide registration of births and deaths began in 1920 in New Mexico, though compliance improved gradually over time. The New Mexico Department of Health’s Bureau of Vital Records is a key resource for post-1920 records.
Seek County Clerks for Marriage Records: Marriages in New Mexico have traditionally been recorded at the county level. Check county clerk offices for marriage licenses and certificates.
Look into Church Registers: Prior to state registration, Catholic parish records can serve as vital substitute sources for baptisms, marriages, and burials. Local parishes may keep these records, or they might have been consolidated in diocesan archives.

Census Records – Federal and StateCensus Records – Federal and State

U.S. Federal Census: Federal censuses in New Mexico began in 1850 (though coverage was more limited until statehood). The 1880, 1900, and 1910 schedules, in particular, are pivotal for pre-statehood ancestors.
Territorial and State Censuses: New Mexico conducted several territorial censuses. While these are not as comprehensive as federal censuses, they can fill gaps. Check state archives and local repositories for copies.
Utilize Searchable Databases: Online platforms often hold digitized census records. Always note any original spelling variations—Spanish names and Indigenous surnames may be indexed in unexpected ways.

Immigration and Naturalization RecordsImmigration and Naturalization Records

Look for Spanish and Mexican Residency Documents: Prior to U.S. control, Spanish and Mexican authorities might have issued land grants or other documents conferring residency rights.
County Court Naturalizations: After New Mexico became a U.S. territory, immigrants could apply for citizenship through territorial or federal courts. Naturalization papers can be found in county courthouses or at the National Archives’ regional branches.
Examine U.S. Citizenship Certificates: For 20th-century immigrants, consult U.S. Citizenship and Immigration Services (USCIS) records, though they often require a Freedom of Information Act (FOIA) request.

Military RecordsMilitary Records

Identify Conflicts and Militia Service: The Civil War, Indian Wars, and conflicts related to the Mexican Revolution might yield service records. Check muster rolls, pension files, and service records in state or national archives.
Look at Federal Military Records: The National Archives holds records for veterans of federal service, including Spanish-American War and World War I and World War II draftees.
Use Veteran Organizations and Historical Societies: Some local historical societies maintain specialized collections of diaries, rosters, and memorabilia.

Land and Property RecordsLand and Property Records

Study Spanish and Mexican Land Grants: Land grants in New Mexico date to the Spanish colonial era, making them vital for tracing ancestral land ownership. The New Mexico State Records Center and Archives (NMSRCA) and the State Land Office hold many original grant documents.
Check County Deeds and Patents: Once counties were established, most property transactions were recorded in deed books at the county clerk’s office.
Use BLM Records: The Bureau of Land Management’s General Land Office (GLO) website provides searchable federal land patents.

Court RecordsCourt Records

Identify the Proper Court: Judicial district courts or county courts handled civil and criminal matters. Depending on the time period, Spanish colonial courts or Mexican-era courts could have relevant records (often found in state archives).
Search Court Minutes and Dockets: These logs can reveal lawsuits, guardianships, divorces, and adoption proceedings.
Check Indices and Finding Aids: Many courthouses maintain indexes for older records. Before an in-person visit, call ahead or search online to understand the materials available.

Wills and Probate RecordsWills and Probate Records

Consult County Probate Files: These detail the distribution of assets after a person’s death. They can provide next-of-kin names, property descriptions, and personal possessions.
Check Historical Probate Records: In older courts, wills may have been filed in a separate “will book” or among general court papers. Ask the county clerk for the exact location of these records.
Examine Translation Issues: Spanish-language wills from the colonial and Mexican periods may require translation. Ensure you have accurate transcriptions to avoid missing key genealogical details.

Tax RecordsTax Records

Identify Potential Gaps: Because tax records are often annual, they can help fill the time between censuses.
Find Land Occupation Clues: Tax lists may show property ownership, acreage, livestock, or other taxable assets.
Accessing Tax Rolls: Many county courthouses preserve historical tax rolls. The state archives may also have microfilmed copies.

Church and Cemetery RecordsChurch and Cemetery Records

Focus on Catholic Parish Registers: Catholicism was predominant in New Mexico under Spanish rule and remains influential. Parish registers can include baptism, marriage, and burial data for multiple generations.
Look into Protestant, LDS, and Other Denominations: Later migrations brought Methodist, Presbyterian, Latter-day Saint, and other faiths. Investigate their repositories for membership rolls.
Map Out Cemeteries: Local genealogical societies often inventory gravesites. Find these lists in published books, historical society collections, or online cemetery databases (e.g., BillionGraves).

African-American and Indigenous RecordsAfrican-American and Indigenous Records

Begin with NARA Record Group 75 (Bureau of Indian Affairs), primarily stored at the Rocky Mountain Region office in Denver, Colorado. Some materials—such as those from the Santa Fe Indian School and the Albuquerque Indian School—have been digitized and can be found on the National Archives site. Additionally, the “Online Archive of New Mexico” offers a range of tribal records, census data, and documents that have been microfilmed by the Family History Library.

Explore Mission and Indian School Records: Indigenous peoples in New Mexico may appear in Spanish mission registers or in documents related to boarding schools. Government agencies (e.g., the Bureau of Indian Affairs) also keep records.
Use Freedmen’s Bureau and Post-Civil War Sources: For African Americans arriving after the Civil War or living in military outposts, Freedmen’s Bureau documents or Buffalo Soldier military records may be relevant.
Investigate Tribal Enrollment Records: For tribal members, enrollment lists and tribal roll books can confirm lineage. Reach out to each specific tribal government for details.

Historical NewspapersHistorical Newspapers

Utilize Digitized Newspaper Platforms: Websites such as Chronicling America (by the Library of Congress) and state digital newspaper repositories often hold searchable archives of New Mexico papers.
Examine Obituaries and Announcements: Obituaries often name surviving family members and detail migration paths.
Search Community Columns: Small local newspapers can contain announcements of births, marriages, local achievements, and social events that illuminate daily life.

Local and State RepositoriesLocal and State Repositories

If your search focuses on New Mexico after it became a U.S. territory in 1848, the Records Center is an excellent first stop. Because of the area’s strong Spanish influence, Catholic records are plentiful, many preserved on microfilm at the center. These can serve as a viable substitute for standard vital records. The facility also houses County Records, District Court Records, Wills, Diaries, and private collections. Before reaching out, consult “Tracing Your Ancestors: Genealogy”

New Mexico State Records Center and Archives (NMSRCA): The primary repository for Spanish and Mexican-era documents, territorial records, land grants, court cases, and more.
State Library and University Archives: University of New Mexico libraries, for instance, hold extensive microfilm collections and rare manuscripts that may assist genealogical research.
County Courthouses: The best source for local records—especially land deeds, probate, and marriage licenses—often has minimal online availability. Plan for potential in-person visits.

Genealogical and Historical SocietiesGenealogical and Historical Societies

New Mexico Genealogical Society: Offers educational programs, research guidance, and sometimes publishes local historical or genealogical journals.
Local Historical Societies: Groups based in individual counties or regions often index records or maintain unique manuscript collections.
Online Forums and Mailing Lists: Many societies sponsor message boards or mailing lists where you can post queries or collaborate with others.
