That seems a little unlikely - simply because, as you say, there is no link between the two girls. So why has Google made that link (when I am sure a large number of people with the same name exist).

What it could be is your girlfriend Googled her name while logged in (i.e. rather than matching the two it just recognizes it as something she searched for). Even that seems unlikely - how does Google know you mean that person when Googling her - does she even have her name registered with Google. and so forth.

There are so many variables I really think that, using Occams razor, it is a highly unlikely solution :)

Also; Wonder Wheel has always given very slap dash to me. I've not observed this level of sophistication in it before...

Would you consider giving the name(s) to someone you trust (but not nearby) for them to perform the same search. That might give us some better data to figure it out.

EDIT: email is on my profile if you want me to check.
