You might well be right, Mike! With my ragbag of a mind, I'd probably have eventually pulled the right bit of thread...

It has always struck me as being a bit too coincidental that this Somerville should be Irish. The other famous Irish family at that sort of level in the Royal Navy was the Pakenhams (Lord Longford etc.). The eccentric streak they somethimes displayed in modern times goes back a long way!
