Born into slavery in 1807 in Spanish West Florida, in an area that later became part of eastern Louisiana, Silvia was sold at the age of 12 for $550, roughly equivalent to $11,568 in U.S. dollars 2025 according to Wikipedia, 2025).
She later came to Mexican Texas as the enslaved property of John Cryer. Between 1826 and 1829, she met John Ferdinand Webber, a white settler and business associate of Cryer. By 1834, while Silvia remained enslaved, she had given birth to three children with Webber (Hammack, 2024).
Any account of their relationship must recognize the profoundly unequal and coercive conditions created by slavery. Silvia did not possess legal control over her own person, and under the doctrine governing slavery, her children could also be treated as property. Whatever bonds developed between Silvia and John existed within a system that denied her autonomy and placed her and her children in continual danger of sale, separation, and exploitation.
On June 11, 1834, Silvia and John negotiated with Cryer to secure freedom for Silvia and their three children. Cryer did not demand payment simply in money or land. He required that the Webbers provide him with a two-year-old enslaved boy and provide a three-year-old enslaved girl to one of his relatives (Hammack, 2024). Later records discussed in the Wikipedia account indicate that the Webbers did not deliver the children and ultimately forfeited a substantial portion of their Webberville property to settle the debt associated with Silvia’s and her children’s freedom (Wikipedia, 2025).
This episode exposes the moral horror at the center of slavery: freedom for one Black woman and her children was assigned a price to be paid through the enslavement of other children. Silvia’s story must therefore be remembered not only as one of perseverance and eventual liberation, but also as evidence of slavery’s immense suffering—the sale of children, the commodification of Black bodies, the vulnerability of families to separation, and the ability of enslavers to extract wealth from the human desire to keep one’s family together.
Even after Silvia and her children gained their legal freedom, they continued to experience severe anti-Black racism. The Webber children were prohibited from attending the local school with white children, requiring the family to hire a live-in tutor. Although some neighbors respected Silvia for her intelligence, kindness, and generosity, they did not treat her as a social equal (Hammack, 2024; Wikipedia, 2025).
Conditions deteriorated further after Texas separated from Mexico and established the Republic of Texas in 1836. The new republic expanded and protected slavery, outlawed interracial marriage, and severely restricted the rights that free Black people had possessed under Mexican law. As settlers from the slaveholding South moved into Central Texas, the Webbers faced growing hostility, discriminatory treatment, and threats of violence. They also feared that slave catchers or so-called "Blackbirders" might kidnap Silvia or the children and sell them into slavery (Wikipedia, 2025).
By the early 1850s, the danger had become so great that the family left Webberville and relocated to the Rio Grande Valley. They eventually settled near present-day Donna, Texas, across the river from Reynosa, Mexico. There, they established the Webber Ranch and operated a ferry across the Rio Grande (Hammack, 2024).
Family histories and regional accounts identify the Webber Ranch as a possible station on the southern Underground Railroad. Silvia was widely remembered for opening her home to people who were hungry, destitute, or seeking refuge. The Webbers reportedly fed and sheltered freedom seekers and used their ferry to help fugitives from slavery cross the Rio Grande into Mexico. Their neighbors, Matilda and Nathaniel Jackson, another interracial family, were also known to assist people escaping enslavement (Hammack, 2024; Wikipedia, 2025).
The Webbers were part of a much broader history of resistance. Research on the Underground Railroad to Mexico demonstrates that Mexican residents and Mexican Americans participated in these freedom networks. People of Mexican descent guided escapees, shared information about routes and conditions across the border, offered food and hiding places, and sometimes helped freedom seekers evade slave catchers. Some endured intimidation and violence from slaveholders precisely because they assisted enslaved Black people seeking freedom (Baumgartner, 2020).
This history is important because it challenges the familiar geography of the Underground Railroad, which is usually imagined as moving north toward free states and Canada. It reminds us that another vital path led south through Texas and into Mexico. It also complicates histories that portray slavery and abolition exclusively through a Black-white framework. Mexican and Mexican American communities were not merely observers of enslaved people’s flight to freedom; some were active participants in making that freedom possible.
The story of Silvia Hector Webber therefore reveals a profound history of Black resistance, Mexican and Mexican American assistance, interracial family struggle, and cross-border solidarity. At the same time, it exposes the long reach of slavery and anti-Black racism: the buying and selling of children, the denial of education, the threat of kidnapping and re-enslavement, the dispossession of property, the displacement of free Black families, and the persecution of those who opposed slavery and the Confederacy.
This important history will be addressed this coming Saturday, July 25, 2026, with Webber family members and descendants present at the Emma S. Barrientos Mexican American Cultural Center in Austin. The symposium, “Visibilizing a Freedom Fighter, Silvia Hector Webber: A Legacy of Resistance & Black Freedom in North America,” will bring descendants, scholars, genealogists, and community historians together to honor Silvia’s legacy and deepen public understanding of Black freedom-seeking, Mexican American solidarity, and cross-border resistance.
The free symposium will take place from 10:00 a.m. to 7:00 p.m. at the ESB-MACC, 600 River Street, Austin, Texas. As I shared in an earlier blog post, the gathering is part of the Webber Family Preservation Project and will highlight both the Webber family’s history and the important work descendants are undertaking to recover and preserve their ancestral histories, cultures, and historic sites (Valenzuela, 2026).
Source note: This account draws principally on historian María Esther Hammack’s archival research on Silvia Hector Webber, including her discovery and transcription of the 1834 freedom papers that secured freedom for Silvia and her three young children. It also draws on Hammack’s authoritative biographical entry in the Handbook of Texas Online and the Wikipedia entry “Silvia and John Webber.” Broader historical context regarding the southbound Underground Railroad and Mexico’s importance as a destination for freedom seekers comes from Alice L. Baumgartner’s South to Freedom: Runaway Slaves to Mexico and the Road to the Civil War.
