Regular posters might be interested as to how I found out that this Earldom had become extinct.
As a junior member of the Perceval family,descended from a younger brother of the first perceval baronet I was told by my son in march 2012 that I was to expect the birth of a male Perceval grandson in April this year and that he was likely to be named Fred or Frederick.
I duly pressed or rather goggled Fred ,Freddie and Frederick and came up with the death of the last earl,Freddie and his wife Connie,as well as discovering that his sister Geraldine had died earlier in 2011.
