Also - it does NOT mean you are necessarily related to the person, because (as Jelena says) the connection finder uses marriage relationships as well as the blood links.
Related is kind of like connected - on Wikitree Connected means to the one Tree, whereas connected to other profiles might better be termed as attached. Related by blood isn't the same as a relationship by marriages. We need a new term!
(Elizabeth is brand new to the connection finder, as she was unConnected until today.)
