You should use "Which" instead of "Witch". The "witch" is a woman.

There may be certain conventions or accepted ways or transliterating names from your language to English. If you have a passport your name will be written in the Roman alphabet somewhere so perhaps use this spelling.

You are writing your name in English letters so there is no correct or incorrect way.I don't know how you say your name, therefore I cannot tell you which is the correct way to write it in English. The way you write it, it sounds like I should say "Say-for-la-he" is that correct pronunciation?
