"Who was Grace and why was one of the Tudors saving her?

And why would being Welsh have made this so important?"

Grace was saved by a number of Tudors in during a wild storm just off the coast of Pembrokeshire near Manobier Castle (birthplace of Giraldis Cambris who was found in a nest or something) in a boat with many rollocks (t'wern't a coracle like they have on the Tefi Dewi Afon) which they rowed out at no small risk to themselves and when they saved her they all rowed back through the surf and spume and had laverbread and cockles and bacon and a tot of something rum to keep them from getting a chill so that's why being Welsh is important and if you have to ask the question then there's obviously no Welsh blood in you and that would make you like that bloke who lived around the corner from me who hadn't any too.

There's luverly for you!
