Sir C, I had Duke of Aquitaine at 889 years but could be a calendar thing as discussed here times past.
There's no need to pander to SC's 5 year rule, as that is entirely his own invention.
Would you could lay off that, mate. I make no demands you are free to post what you like, including 1 month anniversaries for all I care.
Having no rules means you can post literally every dead person's name every single year. If that's what you want to do, enjoy yourself using your free hand to mouse click. My last words on the matter.
