Some years ago I wrote a program which converts a text file list of
lat long name
to a KML file. Just double-click on the KML file to place the
points on Google Earth.
I've uploaded the program, sample data and KML results to my web site.

I haven't used the program for a long time, so YMMV (or YKMV).
They've updated the Google Earth data so some of my marks are out of date.
