> the only explanation I can come up with is that Google has taken note that my girlfriend and ex may have done Google searches on each other

That seems.... unlikely. Mostly for logistical/practical reasons than anything else.

Were you logged in at the time? That seems more likely.

Did the name pull up actual results on your ex? Is there a more reasonable explanation (i.e. could it be someone else your GF is interested in).

I am not.

It does not.

Of course some other connection between my girlfriend and ex may be possible, but none exist or are record online to the best of my knowledge. The problem with this answer is that all of us have considerably more readily associated information, and even if there is a rare case of indirect connection, it seems unreasonable that Google would weight it so greatly so as to make it one of the 8 Wonder Wheel connections.
