Marq was described as an amiable and good-natured man. He was a devoted father, who loved all his children.
Marq was born a second son of the Lord of Fair Isle. His father and elder brother perished during the Battle Beneath the Gods Eye while fighting for Prince Aegon the Uncrowned, which made Marq the new lord. His eldest son and now his heir, Ser Franklyn, returned the bodies of his kin to Fair Isle for burial.
In 47 AC Lord Marq hosted Princess Rhaena Targaryen. During the princess's stay at Faircastle, she befriended his daughter Elissa and was courted by his second son Androw. They married in 49 AC; however, there were tensions between them and Lord Marq's heir, Ser Franklyn. Marq died in 50 AC, choking on a fish bone at his own table. He was forty-six years old at the time of his death.
