Research Guide
This guide explains how to use Southwest Louisiana Records to search the archives, follow cross-archive links, and trace family lines across the 1865 divide. Whether you're new to genealogical research or an experienced researcher, the platform is designed to surface documentary evidence and let you evaluate it for yourself.
Quick Start
If you're looking for a family name and want results quickly, go to Search and type a surname into the Hebert Archive search box. The Hebert Archive covers 1720–1865 and contains the most records by volume — it's the best starting point for most Louisiana families.
Understanding the Archives
The platform combines three archives that were created independently, for different purposes, by different institutions. Understanding what each archive contains — and what it doesn't — is essential to interpreting the results.
Compiled by Dr. Gwendolyn Midlo Hall from Louisiana notarial records, this archive documents enslaved and freed individuals through legal instruments: bills of sale, manumissions, estate inventories, and freedom papers. It covers the French and Spanish colonial period through the early American period.
What you'll find: Names (often first name only for enslaved individuals), approximate ages, origins (African nation or Louisiana-born), physical descriptions, skills or occupations, and the names of enslavers or witnesses.
Important limitation: Enslaved individuals are frequently recorded by first name only, or with a single name. Surnames in this archive, where they appear, are often those of the enslaver rather than a chosen family name.
Transcribed by Father Donald Hebert from Catholic parish registers across Southwest Louisiana, this archive records sacramental events: baptisms, marriages, burials, and successions. It covers Acadian, Creole, free Black, and enslaved populations who were baptized or married in the Catholic Church.
What you'll find: Full names (surname and given name), record type, year, parents' names for baptisms, witnesses for marriages, parish of origin, and ethnicity classification where recorded.
Important limitation: Coverage is uneven across parishes and decades. Many records from the 1800–1830 period were damaged or lost. Records for enslaved individuals are often recorded by first name only before the 1840s.
The complete 1880 federal census enumeration for Louisiana, covering all 935,068 residents. This is the first federal census taken after Reconstruction and captures the first generation of formerly enslaved families living under their chosen surnames.
What you'll find: Full name, age, calculated birth year, race (White / Black / Mulatto), sex, relationship to head of household, occupation, birthplace, and parents' birthplaces. Records are grouped by household.
Important limitation: Ages were self-reported or estimated by census enumerators and are frequently off by 2–5 years. Birth years derived from census ages should be treated as approximate. Name spellings reflect the enumerator's phonetic transcription, not the family's own spelling.
How to Search
Hebert Archive search
The Hebert search matches against surname and full text. Searching by surname is recommended for most cases — type the surname in the left search box. The full-text box searches within record content and is useful when you know a parent's name, a witness's name, or a specific place name that might appear in the record.
Name matching is accent-normalized and phonetic — THIBODAUX, THIBODEAUX, and TIBODO will all surface related records. French–English equivalents are matched automatically: searching JEAN will also surface records with JOHN, JUAN, and JAN.
Hall Archive search
Hall Archive search works the same way — surname or full text. Because many Hall records contain only a given name for enslaved individuals, full-text search is often more productive than surname search. Try searching a slaveholder's surname to find all enslaved individuals documented in their estate or transactions.
1880 Census search
The Census tab offers two views: Individual Records and Household View. Household View groups records by household ID and is useful for identifying family units and relationships.
Use the filters to narrow by parish, race, sex, or relationship to head of household. The surname search uses a prefix match — searching BROUS will return BROUSSARD, BROUSSAR, and similar. Sort by age or birth year to find individuals in a specific generation.
Cross-Archive Links
Cross-archive links are the platform's most powerful feature. They appear as labeled sections on individual record cards and connect probable matches between archives. There are two active link types:
6,176 confirmed links connect Hall notarial records to Hebert sacramental records. A person documented in a bill of sale or manumission in the Hall Archive may also appear in a baptism or marriage in the Hebert Archive. These links are the strongest on the platform because both archives cover overlapping time periods and populations.
21,987 links connect Hebert sacramental records to 1880 Census individuals. These links cross the 1865 barrier — connecting a pre-emancipation baptism or marriage record to a post-Reconstruction census household. This is the platform's core research contribution for Black and Creole family history.
Understanding confidence scores
Every cross-archive link carries a confidence score between 65% and 99%. The score reflects the strength of the match across name similarity, year proximity, and parish geography. Scores are grouped into two tiers:
Research Workflow
The following workflow illustrates how to use all three archives together to build a family case across the 1865 divide. This approach is recommended for researchers trying to connect pre-emancipation records to post-Reconstruction households.
Freedman's Bureau Records
The Bureau of Refugees, Freedmen, and Abandoned Lands (commonly called the Freedman's Bureau) operated from 1865 to 1872, documenting formerly enslaved people and free Black families during the first years of Reconstruction. Its records fill the critical 15-year gap between the Hebert Archive's 1865 cutoff and the 1880 Census.
What you'll find: Labor contracts between freedpeople and former enslavers, ration and issue rolls, marriage registers (many couples formalizing unions that had no legal standing under slavery), apprenticeship indentures, hospital and medical records, and letters and complaint registers. Louisiana records are concentrated in two microfilm publications: M1905 (Records of the Assistant Commissioner for Louisiana) and M1483 (Records of Subordinate Field Offices, covering individual parishes).
How to access it: Every Hebert record card, 1880 Census card, and person profile page on this platform includes a green Search Freedman's Bureau → button. Clicking it opens a pre-filled search on FamilySearch — indexed by volunteers from the original microfilm — in a new browser tab, with the person's name already entered.
What to expect at FamilySearch
FamilySearch hosts the most comprehensively indexed version of the Bureau records, with individual names transcribed from thousands of documents. Search results will show record type, approximate date, and a link to the original image. You may be prompted to create a free FamilySearch account to view full-size images — account creation is free and does not require a subscription.
Bureau coverage varies by parish and record type. St. Landry, St. Martin, and Lafayette parishes are well-documented. Results are not guaranteed for every individual — many Bureau records were damaged or destroyed during and after Reconstruction, and not all surviving records have been fully indexed.
Tips & Limitations
Name variation
Louisiana genealogical records span French, Spanish, and English administrative periods, producing enormous spelling variation. The same family may appear as THIBODAUX in a French church record, TIBODO in a Spanish-era notarial act, and THIBODEAUX in the 1880 census. The platform's phonetic matching handles most of these variants automatically, but when searches return no results, try alternate spellings or shorten the surname to a distinctive prefix.
Year approximations
Birth years in the 1880 Census are derived from stated ages, which are frequently off by 2–5 years. Cross-archive links account for this uncertainty — a link between a baptism record from 1843 and a census individual with a calculated birth year of 1847 is still algorithmically plausible. When evaluating a link, prioritize name and parish alignment over exact year agreement.
Common surnames
Surnames like RICHARD, LANDRY, BROUSSARD, HEBERT, and TRAHAN are extremely common in Southwest Louisiana. Cross-archive links for these surnames carry a higher false-positive rate than links for rarer names. Apply extra scrutiny — look for alignment in given name, approximate birth year, and parish before accepting a common-surname link as a probable match.
Coverage gaps
Not all Louisiana parishes are equally represented in the archives. The Hebert Archive is strongest for the Attakapas–Opelousas corridor (St. Martin, St. Landry, Lafayette, Iberia). Coverage thins for North Louisiana and the Florida Parishes. If searches for a known family return no results, the records for that parish may not be included in the current dataset.
This platform is a research tool, not a definitive record
Southwest Louisiana Records surfaces evidence and probable connections. Every link, match, and suggestion should be verified against original source documents — church registers, notarial records, census microfilm, or other primary sources. The platform helps you find where to look; the verification is yours to do.
