don't go for some fashy larp name - as kewl as it would be, it won't work
the only things that will work are some degenerate retarded name (the current winner - boatyleboatface) or something suitably honorable
just shoot for something of british nationale:
an ancient pagan hero, christian saint, or euphoric researcher worthy of note
some saint ideas:
Saint Brendan
St. Erasmus
St. Francis of Paola
St. Anthony of Padua
