A charter of 836 has also been cited as evidence that Wiglaf was acting as an independent ruler at that time; it records a council at Croft, in Leicestershire, attended by the Archbishop of Canterbury and eleven bishops, including some from West Saxon sees.
Como evidencia de que Wiglaf actuaba como gobernante independente naquel tempo tamén se citan uns foros de 836; estes rexistran un concilio en Croft, en Leicestershire, ao que asistiu o arcebispo de Canterbury e once bispos, entre os que se atopaban algúns dos bispos saxóns occidentais.
