Alexander or Wamsutta or else Sepaquitt. Their Mark. 

Pokanoket, Wampanoag. His homelands across the southeastern coasts of the places commonly called Massachusetts and Rhode Island. Leader of the Wampanoag confederacy upon the death of his father, Ousamequin in 1661. Suspected by colonizers of Mass. Bay colony of colluding with the Narragansett against them; Wamsutta also angered European settlers in Massachusetts because of his land transactions with settlers in so-called Rhode Island. Wamsutta died suspiciously in 1662 after being detained and questioned by English settlers. 

Their kin: A partner, Namumpum or Weetamoo. Their father Ousamequin, the Massasoit. Brothers Pometacom (or Philip) and Sonkanuhoo; sisters Amie and another whose name I am so far uncertain of. 

This deed signed by Wamsutta on January 20, 1661, for lands bounded by the so-called “Seven Mile River ….southward till it come to the main sea, and then to run by the sea westward to Seconet.” John Sassamon is listed as “Interpreter Indian” at the signing of the deed.
