My First Name
Like Psychotoddler, I too go by my given name; a name that certainly is not Jewish.
I am called by my Hebrew name when I get an aliya in shul and sometimes by people who insist that this is my true name. Nevertheless, I prefer to be called by my given name because I was never given a Hebrew name by my parents.
Recognizing the fact that I needed a Hebrew name in shul, I picked one for myself when I was a teenager. Since all my grandparents were still alive at this time, I did not choose a name of a deceased relative. Rather, I picked the name of a soldier from the Irgun Zvai Leumi who was hanged by the British in 1947 whom I admired. While I continue to use this Hebrew name to this day, I only use it for "religious" matters.
I am sometimes asked whom I am named for when people hear my given name. The answer is quite easy: no one. When my father was growing up, people added a "y" to his name as a diminutive. This bothered him some much that when I was born his only stipulation in naming me was that I be given a name that did not have a diminutive. He did not want a son who people would refer to as Johnny, Bobby, Mikey, etc.
Although my given name has absolutely no significance, it is my name; the name I prefer to be known by; the name I have answered to for the past thirty-three years.
