Sven,
I have that tech savvy, but ironically, since I use my iPad almost exclusively, I can't get to the details that would enable a solution.
Basically, if you bring up the map and choose the Download KML link, you can launch the map in Google Maps. In theory, then, you could address a specific placemark by building the URL to reference the KML file and adding a #course name qualifier to the URl. In code, I can do that, but since I am confined to the iPad, I'm stuck using what Google gives me (which is pretty darn amazing).
The map markup language KML (Keyhole Markup Language) supports a ton of cool features:
Time stamps
Time Spans
Camera Views
Image Overlays
Tours
Google Earth is the de facto rendering engine (as opposed to a browser). If you think about the above features, you can do things like:
Build a timeline of courses for an architect, where you could use a slider to make the courses appear (and disappear) on the map as you look at any point in time.
Place and orient pictures in a photo tour on the map
Twist, and stretch the old maps and drawings and place them on the map.
Build a guided tour of an architect's career, or maybe the history of a course (Pine Valley, perhaps?).
My dream for this is to build out a collaborative, structured data collection of the history of GCA. The map is a first step. I now have 749 place marks for golf courses. That's 749 publicly available data points, enriched a little with some Archie info, dates, etc. And of course, embellishing the data with the references back to the World's most valuable collection of unstructured GCA content.
What you are doing is another important element, getting a more comprehensive list of architect's work catalogued in an accessible format. My original thought was to collect data much like yours, architect's and dates engaged on courses including type of work. To me that makes what you are doing even more cool - you are actually doing it!
Anyway, here's some data: McGregor Links is Dev Emmet 1921, and Mungo Park did Duchess CC in 1897.
If I get on a PC I'll see if I can figure out the linking thing.
