They may have shared their range with the Suma, whose history is quite similar. The people whom Espejo called the Tampachoa were probably the same people encountered by Juan de Oñate in the same area in May 1598; he called the natives the Manso. Onate and his large expedition forded the Rio Grande near Socorro, Texas assisted by 40 "manxo" Indians. Manso meant “gentle" or "docile" in Spanish. Their name for themselves is unknown. In 1630, a Spanish priest described the Manso as people "who do not have houses, but rather pole structures. Nor do they sow; they do not dress in anything particular; but all are nude and only the women cover themselves from the waist down with deerskins." In 1663, a Spaniard wrote of them,  "The nation of Manso Indians is so barbarous and uncultivated that all its members go naked and, although the country is very cold, they have no houses in which to dwell, but live under the trees, not even knowing how to till the land for their food."The Manso were also said to eat fish and meat raw. But they were described somewhat favorably as "a robust people, tall, and with good features, although they take pride in bedaubing themselves with powder of different colors which makes them look very ferocious." During the 1660s, hundreds of Manso converted to Christianity. The Spanish established a mission among the Manso. The people were of minor concern until the 1680s, when the survivors of the Pueblo Revolt in New Mexico took refuge in the new settlement of El Paso. There the Manso established close relations with the refugee Piro and Tiwa (Tigua) . It is likely that trying to support the 2,000 Spanish and Indian refugees in this area was difficult. The colonists noted that the Manso living at the Mission were "trouble-makers," along with the Apache and Suma still living in the mountains and the deserts. In 1682, the Governor in El Paso reported that the Manso and the Suma had revolted and attacked the Jano. On March 14, 1684, friendly Tiwa and Piro told the Governor Domingo Jironza Petriz de Cruzate of a Manso plot to kill all the Spaniards in El Paso. The Manso were said to be “tired of everything having to do with God and with the church, which is why they wanted to do what the Indians of New Mexico had done.”
