It is somewhat difficult to do a search for yourself
on the net, mainly because you won't be looking in places that are really obvious

of the local Royal Canadian Cadets
organisation, and they have a web page with your name and email address on it. So it is really better to ask someone who doesn't know you too
well to try and dig up everything they can on you.
On that note, here are some good starting points:
I am yet to find a good reason for trying to dig up all the information on yourself on the web, unless of course you're trying to completely change your net-identity
and need to remove all the tracks
of you currently on the net.
