Lord Yaxley

Sir P. G. Wodehouse never got around to writing about it...But based on what he did write, it seems that upon the death of his Uncle George, Bertie will become Lord Yaxley, being the oldest male nephew...I always found this amusing and wish Wodehouse had taken the stories in that direction. I'm sure he would have come up with something hilarious.

This is exactly what happened, and you can read about it in C. Northcote Parkinson's biography of Reginald Jeeves: Jeeves: A Gentleman's Personal Gentleman
