Most people who search for Maria Catarina Charguana are following a thread that leads back to one of the most recognizable names in American history—Sacagawea. But Maria herself is worth understanding on her own terms, not just as a footnote to someone else’s fame.
Her life is documented mainly through a single baptism record from a California mission in 1848. That record, combined with decades of genealogical research, tells us who she was, who her parents were, and why historians and family researchers are still talking about her today.
What the Records Show About Maria Catarina Charguana
The confirmed facts about Maria Catarina Charguana start and largely end with one document: her baptism entry at Mission San Fernando Rey de España, located in what is now Mission Hills, Los Angeles County, California.
She was born on 4 May 1848. Her baptism was recorded on 28 May 1848 by Father Blas Ordaz, listed as entry #1884 in the mission parish register. That record is the primary anchor for everything we know about her identity.
Her name appears in several forms across historical and genealogical sources: Maria Catarina Charguana, Maria Cantarina Charguana, and Maria Catarina Charguana Charbonneau. Some research also suggests she may have used the surname Meyer at some point in her life, though this detail comes from secondary sources rather than confirmed primary records.
Both FamilySearch (profile LXM3-YRG) and Wikitree (Charbonneau-985) confirm her birth date and location. No widely accepted death date exists. Wikitree lists her date of death as unknown.
Her Parents—Jean Baptiste Charbonneau and Margarita Sobin
Maria’s mother was Margarita Sobin, identified in genealogical sources as a Luiseño Native American woman who was approximately 23 years old at the time of Maria’s birth. The Luiseño are an Indigenous people of Southern California, connected to the broader coastal mission communities of the region.
Her father is identified in multiple sources as Jean Baptiste Charbonneau—the son of Sacagawea, born during the Lewis and Clark Expedition in 1805. This connection is the main reason Maria’s name surfaces in historical and genealogical research today.
It is worth noting that some sources use careful language around this identification. Wikitree, for instance, describes Jean Baptiste as “possibly the same man recorded as being the father.” Other sources, including a 2024 biographical essay by Joe Girard and a 2025 article from Dispatch Business, present the connection with more confidence. The honest position is that the paternity is strongly supported by available records but has not been proven with absolute certainty in the way a modern document might allow.
What does support the connection is Jean Baptiste’s known presence in California during this period. He worked in the region in roles including alcalde—a local magistrate position—which places him in the right area at the right time.
Who Jean Baptiste Charbonneau Was—and Why It Matters Here
To understand why Maria Catarina’s story attracts attention, you need a bit of background on her father.
Jean Baptiste Charbonneau was born in February 1805 during the Lewis and Clark Expedition. His mother was Sacagawea, the Shoshone woman who served as a guide and interpreter for the expedition. His father was Toussaint Charbonneau, a French-Canadian fur trader.
Captain William Clark took a particular liking to the infant, nicknaming him “Pomp.” Clark later sponsored Jean Baptiste’s education in St. Louis, and Jean Baptiste went on to live an unusually wide-ranging life. He became a trapper, a guide, and an explorer across the American West. He spent years in Europe as a young man and eventually made his way to California during the mission and gold rush era.
It was during his time in California that he apparently formed a relationship with Margarita Sobin. According to available records, Maria Catarina was born from that relationship in 1848. Jean Baptiste died in 1866, which would have made Maria around 18 years old at the time.
His life represents a remarkable arc—from being carried on his mother’s back across the continent as an infant, to serving as a guide in the same West those explorers opened up. Maria Catarina’s existence is, in part, a continuation of that story into California’s multicultural, mission-era landscape.
Mission San Fernando and the World Maria Was Born Into
Mission San Fernando Rey de España was founded in 1797 as part of California’s Spanish mission system. By the time Maria was born in 1848, the mission era was drawing to a close, but the missions were still functioning centers of community life, particularly for Indigenous people who had been drawn into their orbit over the preceding decades.
The Luiseño people, like many Native Californian communities, had complex relationships with the mission system. Some aspects of their traditional culture were suppressed, while at the same time the missions became places where records were kept, baptisms were performed, and communities gathered. Maria’s baptism being recorded in the parish register is itself a product of that system.
Her heritage layered several worlds together. Through her father, she carried French-Canadian, Euro-American, and Shoshone ancestry—Jean Baptiste’s own background was already multicultural by any standard. Through her mother, she was connected to the Luiseño people of Southern California. She was born at a moment when California was shifting from Mexican territory to U.S. statehood, a period of significant upheaval for Indigenous communities throughout the region.
People with mixed Native American, European, and fur-trade heritage were not unusual in this era, but they often left sparse records. Maria’s story is a small but real example of how diverse these communities actually were.
What Little Is Known About Her Later Life
Beyond the baptism record, documented details about Maria Catarina’s life are thin. Genealogical research suggests she may have married into the Trujillo family, and some sources mention possible connections to the Meyer or Meyers surname. However, as Joe Girard’s 2024 essay notes, her descendants effectively “disappeared into the mist” of the historical record.
This is not unusual for people of her background and era. Indigenous women and mixed-heritage families in 19th-century California were often underdocumented. Their lives were real and full, but the records that survive are fragmentary at best.
She was not a public figure. She did not hold office or gain public recognition. Her significance today is genealogical and historical—not because of anything she did in a public sense, but because of who her family was and what that lineage represents.
Why Genealogists and Historians Still Discuss Her
There are a few different groups of people who search for Maria Catarina Charguana today.
Some are descendants—people tracing Trujillo, Meyer, or Luiseño family lines back through Los Angeles County, who eventually arrive at her name and realize they may be connected to Jean Baptiste Charbonneau and, through him, to Sacagawea. That kind of discovery can genuinely reshape how a family understands its own history.
Others are Lewis and Clark enthusiasts or Sacagawea researchers who want to follow Jean Baptiste’s story past the well-known chapters. Maria Catarina represents the quieter, less-documented continuation of his life—evidence that the famous expedition’s legacy extended into communities and families that history largely overlooked.
The work of piecing her story together is a good example of how genealogical research actually functions. A single baptism record—entry #1884, signed by Father Blas Ordaz—becomes the foundation. Cross-referencing databases like FamilySearch and Wikitree helps confirm name variants and family connections. Secondary sources like Joe Girard’s essay and coverage from outlets like World Business Voice help synthesize what scattered records suggest. And where gaps remain, responsible researchers acknowledge them rather than filling them with assumption.
That combination of careful sourcing and honest uncertainty is exactly what Maria Catarina’s story requires.
A Life Worth Remembering Carefully
Maria Catarina Charguana was born in the spring of 1848 at a California mission, to a Luiseño woman and a man who was almost certainly the son of Sacagawea. Her baptism was recorded. Her heritage was remarkable. And then, for the most part, her story went quiet.
She was not famous. She did not seek to be. But her existence is a meaningful piece of a larger picture—one that includes the Lewis and Clark Expedition, the mission-era California Indigenous experience, and the complex, multicultural communities that formed in the American West long before anyone thought to document them carefully.
For genealogists, she is a connection point. For historians, she is a reminder that famous stories have quiet continuations. And for anyone simply curious about who she was, the honest answer is this: a real person, born in a particular time and place, whose life deserves to be discussed accurately and with care.
