Marton Harrigon is a minor character in the second, third, fourth, fifth, sixth and seventh seasons of Game of Thrones the first-born child and eldest son of Lord Rickard Harrigon and Lady Lorra Wendwater, and the elder brother of Jenelyn, Harren and Braella, and a bastard half-brother, Marwyn Storm.
Marton was the first born son of Ser Rickard Harrigon and Lorra Wendwater, making him the heir to Smithestone after his father. He is the older brother of Jenelyn, Harren, Braella, and has one known bastard half-brother, Marwyn Storm. Like his father, his training and teaching would be far more testing then that of his siblings, being the eldest son, with many things being expected of him once he came of age.
Marton is now squiring for a knight from House Mertyns.
With the death of his grandfather Jothos Harrigon, he became the heir to Smithestone, after his father. Fearing the mortality of his family, a wedding proposal was arranged by his father and Smithestone's Maester. Martin was married to Elessa Luxford, daughter of his fathers Bannerman lord Arrold Luxford, who had just turned 15.
