Want to find my fathers family.... Please Help?

Look on mylife.com or type his name in Pipl.com. Mylife.com or Pipl.com should be able to tell you some of the names of his other realtives closest to him. I found my daughters fathers family (his sister specifically. Her name was listed under his name as closest relative. I found her social networking site and everything) that way. Pipl is an internet search that searches the whole entire internet for any information the whole entire internet can contain on that person you are looking for.
