Here's what I found on the meaning of Tahquamenon. Hiawatha built his canoe "by the rushing Tahquamenaw." The spelling was a variation of Tahquamenon, which comes from an Ojibwa word meaning "dark berry." But in Chippewa, 'Marsh of the blueberries' revealed as the french spelling of Tahquamenon on a map in 1671. The first written record of the name appears as "Outakouaminan"
