Um- Lili'uokalani and Ka'ahumanu were both Hawaiian queens, those names are kinda normal there.
Of course, I don't speak for if it's parents jumping on the Hawaiian trendoid bandwagon, a la Helen Hunt naming her kid Makena'lei "after the Maui town" (I am 99% sure there's no such town. There is a Makena Beach on Maui, that's about all I can think of).
