Thomas Óge Martyn, Mayor of Galway, fl.
In 1558 he obtained a grant from Queen Mary to build a mill on the west side of the Corrib river, on condition that he build a new stone bridge defended with gates and battlements.
It was completed in 1562 and bore a plaque declaring that Thomas Óge and his wife Evelina Lynch "caused this bridge and mill to be made".
He served as a master of Galway from 1550 to 1577, after which he disappears from the town records.
He was the father of William Óge Martyn and Francis Martin, both of whom were later Mayors of Galway.
