Solution 2:

Wyandotte people were forced to move due to conflict with other tribes (including the largest tribe of all, the US government.)

They eventually settled in one place, and formed a nation. So they were settlers in a sense.

However, to arrive there they migrated.

Although the word has a recent connotation equating it with refugee, or even farm worker,

Migrant is

a person that travels to a different country or place, often in order to find work

-Cambridge on-line

The word can also be used to refer to a type of seasonal behaviour, such as the what the Sioux Plains Indians engaged in,

They were a hunting people and traveled frequently in search of their main food source, the sacred American bison or buffalo.

...and the American Buffalo followed migratory feeding patterns.
