Tantamous

"[5] Around 1635 Tantamous and/or his son Peter Jethro was present with a group of Native Americans to witness the sale of what is now downtown Concord to local colonists.

[7] In 1659, John Smith of Charlestown unsuccessfully requested the Massachusetts General Court to deed him Tantamous' land near Sudbury as payment for a debt.

[9][10] Later in life, Tantamous and twelve of his family members lived on the northwest side of what is now named Nobscot Hill, located in Framingham and Sudbury.

In 1675, Tantamous and ten other Indians were falsely accused of committing a murder in the Lancaster Raid after allegedly falling under suspicion due to their "singing, dancing, and having much powder and many bullets and slugs hid in their baskets," but they were acquitted when the true murderer, Monoco, a Nashaway, was discovered, and Peter Jethro actually communicated with the captors of Mary Rowlandson to obtain her release.

Daniel Takawombait signed a letter to John Eliot requesting that church services in the Natick Praying town continue in the Nipmuc language rather than English, and one of the signatories was "Olt Jetro,"[23] so Peter Jethro may have used his father's name after his death or another Indian may have adopted it as was the practice among other New England Indian leaders of that era.
