Richard, thank you so much for this list and your additions.
As I was going through Debrett's, I remembered the Haig, Alexander of
Tunis and Montgomery of Alamein peerages had been created for military
commanders of the last century. I also noticed that they were also
marked for extinction within the next few decades (if not sooner) and
wondered how many others were in a similar situation.
Taking your list, Richard, and comparing it to Debrett's, here's what
I found (corrections welcome):
WWI
In good condition (with young heirs, etc. ):
Mar of Milford Haven, etc.
