I have a friend who I am trying to look up, and when I enter their name in the phone book, Kelli smith for example,. it says no listings. But it does shw me in the phone book the name K smith. But when I go online to see what the K stands for, it tells me the same thing. Now I’m not stupid, I know the parents did not name their kids "K" smith. And theres so many people with K smith (not hte real name obviously, smith is just for example purposes) that I would end up calling a dozen or more people just to find out what the k stands for. Is there anyway online to find out what this letter stands for without paying a fee?
I tried that site whitepages.com but it didnt work. Any sites that will work will charge a fee though. Is there anything free? is there a phone number I can call?
