I have someone's first and last name. How can I find their social media profile?

I use there name age date of birth and there city and state they live in or have lived in. The more you know the easier it is to find someone on the internet. Old address old phone numbers. Past schools colleges place of employment. . It isn't easy with just a first and last name Google search. Comes up with 1000s of people. . Do you got old email address some times that helps. . .
