Well, I liked the look of Talia, but I assumed Thalia was pronounced the same. I thought Talia was cleaner, but realise one is Hebrew & the other Greek. Pronounced (forgive if I get the emphasis wrong) tah-LEE-ah -- same sound as in Natalia
I mean I would assume it was pronounced sort of like Dhalia. I just thought it might be worth mentioning since the comments on Thalia say it's pronounced "tha-LYE-uh"
