I thought it was butt zee too!!!
Leya= Leah or Lee-A
Mine are Tsekani (Sekani) and Sohni (Sony)
The dogs are Asha, Chloe and Midge
My horse's name is Tacia, which I pronounce Taysha, but her breeder pronounced it Tah-see-ah. I just find that it's easier to just pronounce it with 2 syllables, and my breeder said I could call her anything I want.. (=
BTW - I completely thought it was Butt-zee. With that spelling it's pretty natural. Bootsy is a much nicer name.
