Four main Tsimshian clans form the basic phratry. A related word in Khanty denotes a specific phratry. The Hackensack were a phratry of the Unami tribe of the Leni Lenape. The Turtle phratry was considered the senior clan, with the role of leading the tribe. Among Native Americans, a phratry is often identified by a nature sign. However, a reference in the text to "Poseidon Phratrios" continues to support the phratry theory.
