If you know at least 3 generations of your ancestors and have a face book account, add the Relatively Me application, it will, in time, connect you to oodles of people, but be warned it is only as factual as the information that has been uploaded to One Great Family. I uploaded a gedcom file of about 200 individuals I know I am related to back to the 1500's on both sides of my family and Relatively Me now lists 73609 ancestors and 185 generations,,,,,,much of which is just good for a laugh, such as individuals known only as Visigoth or Guntharr,, and it will inevitably connect you to Adam,,,which may be due to the errant individuals who have posted ill researched genealogical files.
