Said to be of East African origin and meaning “adventurous traveler,” though this is hard to verify; it may just be a modern invention, a spinoff of names like Imani. Either way, the “adventurous traveler” meaning will likely be true, as your little Kymani will want to explore every place he can reach, even if it’s no further than your own back yard.
Famous people named Kymani:
Reggae singer Ky-Mani Marley, and his son, Ky-Mani Marley, Jr.
The popularity of this name can singularly be traced back to son of Bob Marley, Ky-Mani Marley; it appeared on the top 1000 charts in 2008, shortly after his album "Radio" topped the reggae charts.
