The Mark of Martyn is a mark carried through the blood of House Hayford, and in the last few decades alone, has come to be the defining identifier of all true Hayfords.
First seen in Martyn Hayford- the father of the current Lord of Hayford, Harrold- the mark is a distinctive slash through the color of the person's right eye, always found protruding from the center of their eye, down to wards the bottom left of it, (bottom right to whomever is looking at the eye). Though the Maesters have said that this mark can cause difficulty with vision, it has never affected any of the Hayfords thus far.
