This is my name and I get so many different pronunciations from people. Some people say "Tone-ya", some say "Tahn-ya" and others say "Tawn-ya". All are correct depending on how the person's parents wanted it pronounced, but I pronounce it the last way. No one ever spells it right either! They always want to spell it "Tanya" or "Tonia" and I even had one lady ask me if it was spelled with a y or a j!
