how do i spell my name in HEBREW my name is mireya

Well, it's not a Hebrew name so this is a guess.

Mem is the m sound and Resh is the r sound. Yod is the y sound. The vowels, though, are trickier. The ey part of your name, how is that pronounced? Is it like the a in ape, the e in eat or something else?

There is Mt. Mariah which could be the Rock on which the Temple built on. Is it Mariah, maybe?
