Parallel cousin, also called ortho-cousin, is an anthropological term denoting consanguinial kin who are in the same descent group as the subject and are from the parent's same-sexed sibling. A cross cousin is from the parent's opposite-sexed sibling. Simply put, a parallel cousin is a first cousin who is the child of the father's brother (paternal uncle's child) or the mother's sister (maternal aunt's child), while a cross cousin is the child of the mother's brother (maternal uncle's child) or of the father's sister (paternal aunt's child).
