Because turkey day, here's some biography facts about Tisquantum ("Squanto") you may not have learned about in school. (Copy/pasted because I'm lazy)
Tisquantum, more commonly known as Squanto, was a member of the Patuxet tribe best known for being an early liaison between the Native American population in Southern New England and the Mayflower Pilgrims who made their settlement at the site of Tisquantum's former summer village. The Patuxet tribe had lived on the western coast of Cape Cod Bay, but they were wiped out by an epidemic infection, likely brought by previous European explorers.
Tisquantum was kidnapped by English explorer Thomas Hunt who trafficked him to Spain, where he sold him in the city of Málaga. He was among a number of captives bought by local monks who focused on their education and evangelization. Tisquantum eventually traveled to England, where he may have met Pocahontas, a Native American from Virginia, in 1616–1617. He then returned to America in 1619 to his native village, only to find that his tribe had been wiped out by an epidemic infection; Tisquantum was the last of the Patuxets, and went to live with the Wampanoags.
The Mayflower landed in Cape Cod Bay in 1620, and Tisquantum worked to broker peaceable relations between the Pilgrims and the local Pokanokets. He played a key role in the early meetings in March 1621, partly because he spoke English. He then lived with the Pilgrims for 20 months, acting as an interpreter, guide, and advisor. He introduced the settlers to the fur trade and taught them how to sow and fertilize native crops; this proved vital, because the seeds which the Pilgrims had brought from England mostly failed. As food shortages worsened, Plymouth Colony Governor William Bradford relied on Tisquantum to pilot a ship of settlers on a trading expedition around Cape Cod and through dangerous shoals. During that voyage, Tisquantum contracted what Bradford called an "Indian fever". Bradford stayed with him for several days until he died, which Bradford described as a "great loss".
TL;DR: Tisquantum and Samoset spent part of their 20s escaping a Spanish monastery and making their way back to England to catch a boat ride back home only to find Squanto's people had died off. The Pilgrims made landfall soon after, and Tisquantum earned a sainthood keeping themselves from getting themselves killed for being too British (some diaries mention digging up burial mounds and stealing grave goods).
