If you have sufficient supporting data, like where they work, how old they are, where they live, where they went to school etc., you might be able to narrow it down, but no chance with just a name. I successfully located a woman who I hadn’t seen for twenty-five years and who had re-married twice (hence I had no idea of her full name). I did know her first and second name and the name of her kids as well as her date of birth. That combination of data was sufficient to locate her in just a few minutes – nearly twenty thousand kilometres from where I last saw her.
