Without knowing where your grandmother was from, it's all guesswork, and this information may be of no use at all! - but I can tell you that the majority of people that Google turns up with the name Myrtez are Albanian, and Myrtez seems to be a variant of Myrteza (or maybe it's the other way round?) which seems to be a male Albanian name. It also seems to be sometimes used as a surname.
