I had a similar problem when using the Google Export from Mapinfo.
The only way I could get the labels for the counties
is to put a text label in the Cosmetic layer for each county formated
and placed where I wanted them and then export to kml.
This is useful to get the county names and the proper coordinates.
Note the names are just pushpins with no icon displayed.
In MapInfo I exported the county borders to KML and combined into a
single file. For the two counties in northern California
I show an example below. First I created two icon styles (no icon,
yellow pushpin), then I create to placemarks to create the
County names. The final folder (incomplete as shown) is where you
would place the geometric coordinate data describing the
County borders. Also make sure the default Borders/2nd Level Admen
Regions (Counties) that comes with Google Earth
does not meet your needs.
