Every time I do one of those name searches, I come up as no match for my first name, and about 9 matches for the last name. If I cross out my brother, my kids, my brothers kids and his ex-wives, there are no matches for either my first or last name.
Nobody has my name. Nobody. It is truly unique. It is not my birth name, as I changed it at 29. The names of are of such different ethnic persuasions that the combination exists only once: with me.
