Queen Ka'ahumanu

Kamehameha the Great may have been the king that united the Hawaiian islands under one ruler, but the Maui locals best remember one of his wives. Said to be Kamehameha's favorite wife, the Maui-born Ka'ahumanu[a] is front and center in the unification of the islands and their great leap forward. (Trivia: The Kamehameha Avenue is a fairly unremarkable two-lane street in Kahului. The Ka'ahumanu Avenue is a six-lane road also known as Highway 32.)

A good description of her life and times can be found at Coffee Times[b] and Wikipedia[c], but for the quick and dirty, here are the major points:
