Henry Cyril Paget, 5th Marquess of Anglesey died over a century ago - and seemed, for decades, to be airbrushed from history.
His extravagance - spending his way through a major fortune, what today would be tens of millions of pounds - cost his family dear.
Instead of a military career, he wanted to be not just on stage - but centre stage.
He'd wear gowns made from real gemstones.
He once bought the stock of an entire jewellers shop.
But now - he's become the poster icon for gender diversity, in the National Trust's LGBT History campaign.
And Henry Paget is having a bit of a moment. A musical, written by Anglesey actor Seiriol Davies has been winning both awards and great reviews.
It started last year at the Edinburgh Fringe - and is set to transfer to London's Young Vic next month.....Rob Shelley caught up with Seiriol on the day of the play's last performance - in Caernarfon's Galeri - before it transfers over to the London stage.....
