INBREEDING IN ESCAZU, COSTA-RICA (1800-1840, 1850-1899) - ISONYMY ANDECCLESIASTICAL DISPENSATIONS

We investigate the inbreeding levels in Escazu, Costa Rica, during 180 0-1840 and 1850-1899. inbreeding was researched through analysis of ec clesiastical dispensations and by two isonymy methods (Crow and Mange 1965; Pinto-Cisternas et al. 1985), As expected, the dispensation inbr eeding coefficients were lower than those obtained through isonymy. Ho wever, the three methods indicate that consanguinity increased in the community during the second part of the nineteenth century.
