Genealogy Research Assistance

UTRGV Special Collections & University Archives is happy to assist you with genealogy research, including searching public, church, and archival records. Please note that this research is largely based on secondary source materials that have been compiled by regional genealogical researchers.

In order to expedite your inquiry, please be sure to gather personal information on the individuals or family you are researching, including:

  1. Full Names 
    • First, middle, and last names
    • Maiden Names and/or Parents’ Names 
    • Tip: Consider alternate spellings. For example, it is common for “s” to be used instead of “z.” 
  2. Dates & Locations 
    • Birth (Fecha de Nacimiento) 
    • Death (Defuncion) 
    • Baptism (Bautismo) 
    • Marriage (Casamiento) 
    • Tip: Approximate dates may yield better search results than using exact dates.

Provide as many details as possible for each individual based on the information requested above.

Gather Personal Information

Write down everything you learn. You may use forms available in libraries, genealogical societies, and the internet to record the information. Be sure to always include:

  • Names
  • Dates (birth, marriage, death)
  • Locations (birth, marriage, residence, death)
  • Family names (surnames, also consider alternate spellings)
  • Sources (person, book, or archival collection, etc.  Be specific, include author, title, page number, or collection and folder titles)

Begin with getting as much information as you can from your family members. Ask your parents, aunts and uncles, and grandparents about family members: when and where they were born, were married, etc.

Look for family papers, birth and marriage certificates, personal letters, diaries and journals, photographs, and other sources around the home which may help in constructing a preliminary family history.

Photographs: Write as much information as you can with a soft (#2) pencil on the back of the photograph, including names, date, location, and event.

Review the information you have, and look for gaps, or where information is uncertain or inexact

Federal, State, and County Information

  1. United States Of America Census Information: Census records are an excellent place to begin expanding information on your family.  Begin with the latest census records released, and work backwards to 1850 (the State of Texas was founded in 1848).  Note: the 1890 census was destroyed by fire.
  2. Social Security Death Index (SSDI): After a person's death, their Social Security Number and information are made available as public information. The Social Security Death Index is a database of deaths reported to the Social Security Administration (SSA) beginning about 1962 that have been purchased and made available by various organizations.  For more information about the SSDI, and links to search pages, go to The Social Security Death Index: A Genealogy Records Guide
  3. Texas County Records: The University Library provides access to some county records in electronic and microfilm formats for Cameron, Willacy, Hidalgo, and Starr Counties. Although the specific records vary by each county, they generally contain information such as court documents, marriage records, deed records, and probate minutes.

Texas County Histories from Accessible Archives provides primary source resources for local historical and genealogical research. (If you are off-campus, then you must login using your UTRGV credentials.)
