CHAPAMACO INDIANS. Attempts to establish an identity for the Chapamacos have resulted in much confusion, and even today the problem cannot be regarded as fully solved. In 1708, when first recorded under the name Chapamo, the Chapamacos were said to be one of twenty-nine remnant Indian groups then living in southern Texas, mainly south of present-day San Antonio. No document has been found that gives a more precise location for them. The registers of San Antonio de Valero Mission in San Antonio indicate that at least two Chapamaco individuals, both adult females, lived there between 1730 and 1748. That one of these women is identified in various entries by two names, Chapamaco and Secmoco, seems to indicate that both are variants of the same ethnic name. The second woman is identified by the ethnic name Sepunco, which on phonetic grounds appears to be a variant of the name Chapamaco. Some Chapamacos also entered Spanish missions near the Rio Grande in northeastern Coahuila. One male was recorded at San Bernardo in 1762 and two males at San Juan Bautista in 1772. Through error the name Chemoco has been equated with Secmoco. This resulted from confusing Mission San Francisco Solano of California with a mission of the same name in northeastern Coahuila. Other errors include the equation of Sencase with Sepunco, and Sinicu with Secmoco. No evidence supports either of these equations. J. R. Swanton listed Chapamaco, Chemoco, and Secmoco as three separate Texas Indian groups who probably spoke Coahuilteco. As Chapamaco and Secmoco seem to be variants of the same ethnic name, and Chemoco refers to an Indian group of California, the main residual problem is determining what language was spoken by the Chapamaco. They could have spoken Coahuilteco, but linguists today point out that languages other than Coahuilteco were also spoken in southern Texas. It therefore seems best to say that the language spoken by the Chapamaco remains undetermined.
