What website can I go on to find someone that I've met before but I only know the persons first name...?

A long time ago I met this boy on a beach and he was just so sweet he was the sweetest person that I had ever met in my life. I was maybe 9 years old and he was about the same age and now I will be turning 19 soon. I remember the beach where I had met him, his eye color, race, first name, and his hair color but thats about it. When I was leaving the beach I asked him for his number I was very shy and nervous to ask him I did I called him one time nervously and his dad answered the phone but that was the last time I ever talked to him because i had lost his number.......
