What is the Cherokee spelling for Bonnie?

The name would be BONNIE - Christian / European naming systems to not translate to any Native American language. Native American languages are all noun based, with some descriptors (adjectives, etc). European names are concept related and do not translate, as there is / was, no real concept languages in use. If you were to take the original meaning of Bonnie, which means "Pretty" (or good) then translated Pretty to Cherokee it would be "U-wo-du-hi" or "Eww-ah-do-he" please remember though that this name is not strictly Cherokee as it is a descriptor without a noun, but that is as close as you can get. A real Cherokee name would be more like "Pretty Bird" etc.
