I would suggest ECW/30 years war figures for the settlers along with a mix of figures from Crucible Cruche's Flint and Feather range (some of the English settlers are done with the Pequeot wars in mind)
For the Indigenous peoples I'd suggest Flint and Feather figures too, possibly with a sprinkling of FIW models to give a few more western trade items such as hatchets, shirts, etc
