A person's name is one of the strongest identifying factors there is. Even for people with common names, combining their name with other easily deduced information about them could easily lead to a unique identification. For instance, if you looked through my HN or reddit comments, you could easily figure out roughly what area I live in, my occupation, my approximate age and many other pieces of information that would link back to my real identity. That information combined with my real name would uniquely identify me even if I had an extremely common name.
