Alan Wilson says in his books that the ancient Welsh historical record written by the monk Tysilio (c. 548 -
640) is the most accurate when it comes to Brutus (Brwt - Bryttys),
Eneas (Aeneas), Essgannys (Ascanius), Ssylliys (Selys Hen - Silvius - Ascanius´ son) .... and the much later King Llyr
... so ... BRWT comes before Brutus Darianlas. After Dafyd comes Blaiddyd and after Blaiddyd comes Llyr ...
