Finding Living Relatives

(While this is a Carnival of Genealogy post, it can also double as a part of Craig Manson's theme of "Greatest Genealogical Find Ever")

I've found a number of new cousins in the US over the course of my short genealogy career - almost 6 years now.  Most of these were also pursuing their family histories, and since we were looking for many of the same surnames on the various genealogy websites, it's not too surprising we got into contact.  The most exciting discovery I had, however, happened almost completely by chance and involved a 61 year old letter posted on my simple family history site and Google.  I'd like to say it was my expert research skills that located the descendants of my grandmother's sister in the small town of Pedace ( located a little below the ankle of the Italian boot).  The reality is someone else (not even related to me) started the sequence of events that lead to what I consider my greatest genealogy discovery.
