The fact that there aren't any other Andrew Margalits out there isn't all too suprising to me. I can think of about 6-8 other Margalits I've heard of in the U.S. who aren't related, but alas the last name is primarily found in Israel ... though in some Jewish Communities (Los Angeles, from what I've seen online, primarily. Of course, this might just be a misconception on my part...), Margalit ("ruby") is a semi-popular first name.
Funny thing about names... my father had petitioned for me to be named Vladimyr, which I would have opted for were I to have had any say. Still, Andrew works well enough.
