It would be a mistake to assume that any Hebrew name matches
any particular secular (English, German, etc.) name. For
example, my grandfather and my wife's grandfather were both
called "Leon", but one was "Laib" in Yiddish and the other
was "Lazar." I had a high school classmate whose Hebrew name
was Mordechai and whose English name was Gary. One can simply
never guess at these things.
