The best way to add information to your family tree from SmartMatches that you received is to use the Contact Webmaster link and get in touch with the webmaster of the family site where you have matches. That way, you have a good chance of getting more information than you may have thought available and you will be able to verify the validity of data added to your tree. Not to mention, it’s always great to make new acquaintances with people who share your family history.
