The one item that stands out to me is their mention of Lovebug. Had you written about it in a local file on your computer or in a conversation online at some point? If not, did you use it in one of your passwords or secret questions to an account at some point?
I agree; this would be a great idea.
Something else to consider is maybe people live in multiple locations. For example, I spend a lot of time in Kentucky, but I'm also in New York every other week.
Anyway, ideas are good.
