Anyone Using KML Files For Family History?

I'm in the process of creating a KML file to identify all of my im****tant 
family history locations.  For people not familiar with KML, it's Keyhole 
Markup Language, something akin to HTML or XML but it's used in
conjunction 
with geographic browsers like Google Earth.

My plan is to start with only Placemarks but add images later on.  Has 
anyone done this?  I'm especially interested in hearing from anyone who
has 
shared their KML file(s) publicly as I plan to do.  A URL for such a file 
would be great.  I'd love to take a look at what others have already done 
along these lines.

Thanks,  Mardon
