Hiawatha

This question appears to be based on a misunderstanding. The historical character Hiawatha – a leader of the Onondaga people or the Mohawk people, or both – has no known connection, other than the name, with the title character in the poem by Longfellow, who was based on a character from Native American folklore.

The historical character known as Hiawatha was was a co–founder of the Iroquois Confederacy. This was an alliance between five Native American nations, including the Onondaga and the Mohawk, which dates from the 12th century AD (and is also known as the Five Nations). Longfellow published his epic poem The Song of Hiawatha in 1855; the title character is a member of the Ojibwe tribe, which is one of the largest indigenous peoples of North America and not part of the Confederacy.

Longfellow drew on many sources, including the Ojibwe Chief Kahge–ga–gah–bowh who visited Longfellow's home on several occasions. He originally planned to name his hero Manabozho, which was the name that the Ojibwe used at the time for a "trickster–transformer" figure of their folklore. But he wrote in July 1854 that he thought he would name his character Hiawatha – "that being another name for the same personage."

Wikipedia tells us that "Longfellow, following [an American geographer, geologist, and ethnologist, noted for his early studies of Native American cultures], was mistaken in thinking the names were synonyms. In Ojibwe lore the figure of Manabozho is legendary but the name Hiawatha is unknown."
