What was the name of the American Indian that helped the Plymouth colony settlers?

Tisquantum

Explanation:

The native inhabitants of the region around Plymouth Colony were the various tribes of the Wampanoag people, who had lived there for some 10,000 years before the Europeans arrived. Soon after the Pilgrims built their settlement, they came into contact with Tisquantum, or Squanto, an English-speaking Native American.

its main object was the establishment of "settlement houses" in poor urban areas, in which volunteer middle-class "settlement workers" would live, hoping to share knowledge and culture with, and alleviate the poverty of, their low-income neighbors.
