You need to be careful about posting too much information about living people - it can lead to identity theft. I realize it can be hard to find information if relatives won't talk, but that is their perogative. If you are looking for a living person, it is best to just put down their name and location.
If you are interested in your ancestry, I would recommend starting with your great-grandparents, looking for them in the 1940 census at Ancestry or www.familysearch.org
. If you don't have them already, you could also try looking for their obits, which would give family information.
