xianc78@Jojothegoodperson @louis @p Yeah. Facebook allows you to tag people, including those who have never used the site along with mentioning that you are married, divorced, or widowed with someone who never used Facebook.
If you have ever signed up for Facebook, you would notice that you might get a list of suggestions of people you might know. Most of that data comes from people mentioning and tagging you.
