How can you find out if my Grandfather is still alive for free with the information that i would need to send him a letter or call him plezzz help me?

ancestry.com try the introductory. i did and found my entire family.

If you know the town and state he lives in, call information (411) to get phone number and address. If you don't know where he lives, but have his first and last name, then you type his name in your web browser and start from there (it's free). Also, maybe you could ask your parents or some other relatives. Another option would be to find out where he used to live, and go from that angle. Good luck.
