crowdsourcing the source of the german e-coli outbreak - and finding friends

So i am trying to find someone I knew in france in the 1970s who went by the unlikely first name of Bronte (aka bobo) and looked like this

meanwhile, the source (not spanish cucumbers) of the german awful E-Coli outbreak seems to defeat traditional CDC methods - html>here's a note on why crowdsourcing isn't quite as easy as you might think

for me, the telling point is the 8 day incuation - that means the trail of data you have to look through is huge - on the other hand perhaps looking at location of users' search terms on google might help (and see how many of these people do online shopping - out of 2000, a lot must come from households where one could get that data)

note: privacy is not an issue in a notifiable disease outbreak..in most countries
