Martyn Tyrell and his wife, Florence Fossoway, by Jaydeewis
|Title||Master of coin|
|Born||In or before 43 AC|
|Book||Fire & Blood (mentioned)|
After the murder of Lord Rego Draz, a new master of coin was needed. Septon Barth put forward Martyn who he knew from his time serving at Highgarden; while not praising his wits, he mentioned that Martyn's wife, the Lady Florence Fossoway, had been handling the Reach's accounts for years and had increased the incomes of Highgarden by a third. King Jaehaerys I Targaryen agreed with the septon and summoned Martyn and his wife to court, believing that Queen Alysanne Targaryen would be fond of the intelligent Lady Florence.
Martyn—aided and abetted by his clever wife—proved almost as able as Rego, the so-called Lord of Air, had been as master of coin. This made the Seven Kingdoms prosperous and allowed King Jaehaerys I Targaryen to expand his project of roads, creating the roseroad, the ocean road, the river road, and the goldroad once the kingsroad was completed.
