Today the Cornwalls will vist Kilkenny Castle - and the nearby picturesque village of Thomastown, on the River Nore.
Many in Ireland wonder why they're going to this obscure location - and there are no clues in the media.
However, in 1825, William Dowling was born in Thomastown - and was a recipient of the Victoria Cross for heroism during the Indian Mutiny.
The medal is displayed at the Duke of Cornwall's Light Infantry Museum in Bodmin, Cornwall - and Sgt Dowling is buried in Liverpool.
Could this - I wonder - be the reason for going to this quiet rural backwash?
