Awesome find! The Hohenzollern Yearbook is on my list for when I can read German properly, it seems to have a lot of goodies.

The Borckes and Lentulus I recognize, and Pirch is probably related to our Carel--his father was a Georg Ernst, and this is a Georg Ludwig, so could be a different branch. Selena may know more!

Back to work so I can do German later...
