Graveyard on Guernsey

Extract from "The Nelson Dispatch"2001
I have this year paid two visits to Guernsey & on both occasions i have gone to the churchyard of Ste Marie du Castel to see the grave of Admiral Lord de Saumarez.On my second visit in Mar 2001,my eye was drawn to a grave nearby which contains the remains of servants of the Saumarez family.On this grave among other names ,it was with a shiver of recognition that i saw the following
[center]Also of --Patrick O,Brian who was a faithful and most trustworthy servant in the family for 56 years
?

You have to wonder

Especially as the spelling of O'Brian is less common.

Yes, wasn't that one of the critisisms of O'Brian, that he spelled "O'Brien" wrongly? One would think that such a detail oriented gent as Mr. O'Brian would've known what's what with the Irish names. Surprising this didn't make it into the excellent autobiography (or more likely I missed it).

Hello, BTW!
