This paper analyzes metric femoral morphological variation among historic populations (17th, 18th, and 19th centuries). Variables analyzed in this study include maximum femoral length, epicondylar breadth, vertical head diameter, anterior-posterior subtrochanteric diameter, medial-lateral subtrochanteric diameter, midshaft circumference and the subtrochanteric index. These variables are compared by sex, chronological period, and socio-economic status to assess morphological change and contribute to understanding population variability and the process of miscegenation. In addition, two other comparative samples, one pre- Hispanic from the same study region, and the other, medieval Spanish, are used as references for ancestral groups. The results obtained from the subtrochanteric index make it possible to differentiate between groups with different biological ancestry. These results are discussed in relation to the available historical demographic information and previous bioarchaeological investigations.
