Guerno was the seventh abbot of St-Pierre de Beaulieu, succeeding Bernard I between 948 and 954x967 and going on till 969x970, when Abbot Gerald is clearly in place, although the two share rule briefly in 968 (Beaulieu CIX); matters of dating are complicated by the fact that under neither of them does the abbey's writing staff feel obliged to give regnal years rather than just kings regnant... Guerno's collected appearances are Beaulieu CXLIX, LXXIV, LXX, LXXIII & CIX.
