Iyannough (also Iyanough) was a Native American sachem and leader of the Mattachiest (Mattakeese) tribe of Cummaquid in the area of what is now Barnstable, Massachusetts. The village of Hyannis, the Wianno section of Osterville, and Iyanough Road (Route 132) are all named after him.
Historic records mention the assistance and entertainment offered by him and his tribe towards the Pilgrims and later colonists. When the son of Mayflower passenger John Billington wandered away from the new settlement at Plymouth in January 1621, Iyannough assisted William Bradford and his party in finding the boy.[1] The sachem impressed the Pilgrims as being personable, gentle, courteous, and fair-conditioned.[2]
He died in 1623 when he was only in his mid-twenties. Following a surprise attack by the Pilgrims on the Massachusett tribe that winter, many Native Americans in the region including Iyannough grew fearful of the colonists and fled to hide in the area's swamps and remote islands.[3] It is believed that Iyannough himself died of exposure during this time. Upon his early death his lands went to his eldest son Yanno [4] (aka John Hyanno). Yanno is mentioned in several land deeds on Cape Cod and Martha's Vineyard and appears to have been a prominent figure in the early settlement of the communities.
In the mid 19th century, a farmer plowing his field discovered what is believed to be Iyannough's grave.[5] The gravesite is just north of Route 6A in the Cummaquid section of Barnstable and is maintained by a non-profit organization called "Tales of Cape Cod." A sign along Route 6A marks the spot.
A statue of Iyannough can be found today on the village green in downtown Hyannis.
