Tomassa (– 1900) was a Mexican-American woman who was captured by the Comanche as a child and later integrated into their society. She supported the Fort Sill Indian Agency by helping establish the Fort Sill Agency School, working there as a translator. Tomassa aided in communication between the fort and the Comanche, and was known for her compassion and humanitarian efforts.
Tomassa was born into a well-off family in the Centralist Republic of Mexico.[1] As a young child, she and her older cousin were captured by the Carissa Comanche. They spent a decade with the Comanche and became fully integrated into their society before being ransomed by the Bureau of Indian Affairs and returned to Mexico.[2] No one came to claim them, so they were taken in by a wealthy Mexican family who treated them as servants. She enrolled in school but chose to return to the Comanche. Accompanied by a schoolmate, Tomassa crossed the Mexico–United States border, relying on the stars for navigation, and survived by killing their horses for food and making moccasins from their hides.
At around fourteen, Tomassa's Comanche mother arranged for her to marry a man named Blue Leggings. Defying Comanche traditions, Tomassa refused and instead chose to marry Joseph Chandler (1823–73), a half-Cherokee, half-white farmer near what would become Fort Sill in Oklahoma. Chandler bought her from Blue Leggings for three dollars and a rooster. During the American Civil War, their land was devastated by raiders, and the Chandlers relocated to Texas, returning to Oklahoma in 1868.
Tomassa supported the Fort Sill Indian Agency by helping establish the Fort Sill Agency School. In 1871, she began working at the school as an translator. Fluent in Spanish, English, Comanche, and Caddo, she played a crucial role in assisting the fort's officials and maintaining communication with the Comanche, which helped in preventing raids. Tomassa was known for her compassion, which earned her respect from both the Indian agents and the Comanche. She once sheltered two escaped Comanche captives, treating them with kindness and later helping to secure their freedom.
After Chandler's death in 1873, Tomassa was left a widow with four children. She later married George Conover, a retired army officer, and had several more children. In 1887, she converted to Christianity and joined the Methodist church. Tomassa died in 1900 and was buried on her ranch in western Grady County, Oklahoma.
Tomassa was written about in Indomitable Oklahoma Women which published in 1994 by Western Heritage Books for the Oklahoma Heritage Association.[3]
