From A Wiki of Ice and Fire
Qorgyle was a member of House Qorgyle and was the 996th Lord Commander of the Night's Watch. His given name has not been revealed.
Lord Commander Qorgyle entered the Night's Watch some time before Ser Denys Mallister. During his term, Castle Black used to send patrols east towards Eastwatch-by-the-Sea every third day and west towards the Shadow Tower every second day. It was during his time as Lord Commander that Mance Rayder deserted the Watch, at a time when Jon Snow was already living in Winterfell.
After Qorgyle's death, Jeor Mormont was named Lord Commander in 288AC.
