原The only time I've seen this name is on a white girl and it was spelled a little differently- Quiona- and it was pronounced Key-AH-na. I've never heard of anyone in the [my] African-American culture use this name because of its origin of being a material, and not many peopleI know use this spelling anymore; they use Kiana, Kiyanna, or Keona.
原It's quite clear if you look at the SSA data that Qiana came before Kiana as a popular name, and therefore was undoubtedly derived from the trade name of the silk-like material. This was a computer-generated name chosen to sound elegant and have no meaning in any major language (which is one reason the u-less spelling was chosen). [noted -ed]
