I offered to do a bit of quick research for him. Particularly since through mutual autosomal DNA matches, this genealogist and I think that he and my father might be genetic cousins through this Trujillo line. My friend has already established descent from Lorenzo Trujillo, but I am just beginning to explore my father’s New Mexico Trujillo line.
While Mexican and Hispanic genealogy is a specialty of mine, being from and still living in Southern California, and having no known (until very recently) Hispanic ancestors from Texas, I am not as familiar with records pertaining to the Mexican Army’s role in the Battle of San Jacinto and the Texas Revolution. So I had to spend a little time learning what records might exist in the U.S. pertaining to the Mexican soldiers who fought at the Battle of San Jacinto.
A Google search for “Battle of San Jacinto” quickly led to the following records.
The Texas State Library and Archives Commission (TSLAC) owns the McArdle Notebooks, a collection of “documents, photographs, maps, and personal recollections” obtained from post-Civil War Texas-based artist Henry McArdle. McArdle used these materials for research when painting his best known works Dawn at the Alamo and The Battle of San Jacinto (included at the top of this post). The digitized collection is available online.
The papers pertaining to the The Battle of San Jacinto painting include several items relevant to those researching Mexican soldiers who fought in this battle:
- McArdle’s List of Mexican Officers Killed in Battle
- McArdle’s List of Mexican Officers Made Prisoners
- McArdle’s List of Mexicans in the Painting.
However there is no Trujillo noted on these lists.TSLAC also has a list of “Mexican List of Killed and Wounded at San Jacinto” on its website, included in an article titled “The Battle of San Jacinto.” It is not clear from the website if this list is part of the McArdle Notebooks or if it is from an entireley different source.
Battle of San Jacinto War Prisoner Records
That same Google search also led me to the Texas Archival Resources Online (TARO) site, a one-stop shop for locating finding aids to manuscript collections (most are not yet digitized or online) from a consortium of Texas archival institutions.
The collection that came up in my query is the Battle of San Jacinto War Prisoner Records held by the Special Collections division of the University of Texas at Arlington Libraries. ” Although the collection has not yet been digitized, the online finding aid can help determine if it might be worth making an in-person research visit or hiring a local researcher in that area. The finding aid does not reference a list of prisoners, but it does:
- confirm the type of information the records contain about imprisoned Mexicans,
- confirm that the collection and records are in English (helpful to know, if one does not read Spanish),
- confirm that the collection is open for research, and provides a recommended citation format (wouldn’t want to fly out to Texas only to learn that the collection is not open to researchers),
- provide a detailed Container List that would allow us to prioritize which boxes and folders to ask the archivist to pull for us if we visited the repository.
San Jacinto Museum of History’s Veteran Biographies
The San Jacinto Museum of History’s Herzstein Library provides an excellent online database of profiles for both Texian and Mexican veterans who served in the battle. While most of the Mexican profiles include just brief biographical and service details, dome include photos and a narrative. Unfortunately, I do not find anyone with the surname Trujillo, Trujillo, or Trujio. I do find other veterans with the given name of Lorenzo, but not our Lorenzo.
Does this brief search refute the claim in that book that Lorenzo Trujillo served under Santa Anna at the Battle of San Jacinto, and was taken prisoner? Not at all. A more exhaustive search is necessary, most likely with some in-person research time at UT Arlington and other repositories. I will continue to keep my eyes open for signs of our Lorenzo Trujillo.
But this quick project to help a friend (and possible cousin!) introduced me to some excellent sources for researching Mexican soldiers in the Battle of San Jacinto, some of whom remained in Texas, calling it home, and others who remained in what later became part of the United States.
