How to Track Down a Family Member?

There are ways of tracking people down by using the person social security number. This man is your grandfather, someone in your family should be able to find his number somewhere. An old tax return, a pay stub, something that will show his number will help you find him. The web sites will charge around $20 to find out where that number is in the country. I am not sure but they might nitify him that someone is looking. Give it some thought.
