Kin Groups and Descent. Local groups of extended Families had a base in marriage and blood ties. However, kin groups with economic or political functions above the level of the local group did not exist. Kinship ties were reckoned bilaterally.
Kinship Terminology. Jicarilla kinship terminology followed the Iroquoian system. The father and the father's brother were classed under a single term, as were the mother and the mother's sister. Parallel cousins were grouped with siblings and cross cousins were classed separately. No terminological distinction was made between maternal and Paternal grandparents nor between male and female grandchildren.
