How Do I Handle This Suspicious Friend Request? – Daily Dilemma

The "Daily Dilemma" on the Sean and Richie Show is featured every weekday morning at 6:40am. We and the listeners take on someone's problems and try to offer different perspectives. Now, these don't have to be huge problems- it could just be something bothering you or a friend, or it could be some little thing you and another just can't agree on. If you have a dilemma to share we'd love to hear it just e-mail us here at the show.

Here is today's dilemma:

About 3 weeks ago I accepted a friends request from an individual on Facebook that I had never met before, not too uncommon with the networking I do online. It turned out this guy was just looking for more gaming friends... but anyways, on to the dilemma... After looking at his page, I am 99% sure that this person (let's call him Bob) is my son's paternal uncle - all of Bob's info (d.ob., middle name) matches what I was given years ago when we attempted to find my ex's paternal family & there is a very strong resemblance. Bob lives on the West Coast, my son & I on the East - my son's father ( whom has barely spoken to us since he moved back to Cali years ago) never knew his father or his paternal family- I have no idea if Bob has ever learned he has a younger brother (they are both in their mid 40's now), let alone a 17 yr old nephew - I also have reason to believe that Bob has had little contact with his paternal family throughout the years ( He now goes by his mother's maiden name, no paternal family on his friends list, etc.)... My dilemma should I say something to Bob or just let it go and delete him? I certainly don't want to stir up anything up but at the same time family is family & they say things happen for a reason.
