  • Sekani was the name of a young character in the film The Hate U Give (2018).
  • Amenadiel is a character on the TV series Lucifer.

  • Izhaan is a celebrity baby: Izhaan Mirza Malik was born in October of 2018 to Indian tennis player Sania Mirza and Pakistani cricketer Shoaib Malik.
  • Jardani could be from Jardani Jovonovich, the “real” name of popular movie character John Wick…?
