Yes, my girlfriend and I use GMail.

I am unaware of whether my ex uses GMail or not. We were in school when we met and had uni email addresses.

I just did a search and found that my ex does now use GMail.

I also searched through the contacts and conversations for both my GMail account and my girlfriend's (she consented, of course) - result: in neither did my ex show up.

Are you logged in to your google account while searching?

I have found that the results change when you are and it will promote things that you have search for and emailed about before.

Unfortunately not - I am not logged in when I make the query.

Could you try the same query after deleting all the google cookies?

And flash cookies from all google's domains. Youtube for example.

I sent ErrantX the list of names via email and he has independently confirmed the results.

Looks like it's definitely not a personalized result.
