Meaning of my Name: Dejsha?

Hi, I know my name (Dejsha, pronounced in my opinion like Deja Vu) is unusual. I've only heard of at least 5 others with the same name. I've always wondered what it means. I do know that: My dad made up the spelling from a book which had a similar name: Dejah. The book was Princess of Mars, by Edgar Rice Burrows. I looked up my name the other day and found: Dej (or Dai) is the Chinese word for great, and Sha means King in Persian, although, I am a girl, so would it be translated to great queen? Also, what do you think of my name? My middle name is Chantelle, and I'm a bit undecided if I like it... I know I can't change my name(I could I guess),but I would like to hear other peoples opinions. Also, does anyone know the meaning of the girls name Tamir? I am reading the book the Tamir Triad, by Lynn Flewelling. I love Kai/Ki for a boy(I'm not pregnant) and adore the name Tamir. Any help would be appreciated. Dejsha.
