Relationship on the paternal (father's) side.

Membership to an agnatio depended on a direct blood link to the elder male except that marriage and adoption were two other methods of gaining entrance to an agnatio.

A principle of early Roman law that organized estates based on the father's lineage. Even a wife who entered a family took on the legal status as no more than a sister to her own children in the eyes of the law (see Blackstone's desciption of this in the Legal Definition of Cognates).
