Thomastown (Irish: Baile Mhic Andáin), historically known as Grennan, is a town in County Kilkenny in the province of Leinster in the south-east of Ireland. It is a market town along a stretch of the River Nore which is known for its salmon and trout, with a number of historical landmarks in the vicinity.
The town was founded in the 13th century on an important crossing point by an Anglo-Norman mercenary from Wales, Thomas FitzAnthony, replacing the earlier Irish settlement of Grennan (Irish: Grianán, Sunny Place). It is from FitzAnthony that Thomastown was named.
Milling, with mills powered by the waters of the River Nore, was the principal industry in the town until the early 1960s. The mills were Pilsworth's Mills. At one stage there were 12 water-powered mills, for grain and cloth, working in the parish. The last working mill in Thomastown closed in 1963. This mill is now the site of Grennan Mill Craft School.
For centuries there was an important boat trade to carry produce to and from the port of New Ross. It went into decline at the end of the 18th century. wikipedia

1837 Thomastown
"Thomastown", an incorporated market and post-town, (formerly a parliamentary borough), and a parish, in the barony of Gowran, county of Kilkenny, and province of Leinster, 21 miles (N.) from Waterford, and 59 (S.S.W.) from Dublin, on the mail coach road to Waterford; containing 3054 inhabitants. This place, situated on the river Nore, and on the southern border of the county, was anciently called Grenan; it took its present name from Thomas Fitz-Anthony Walsh, Seneschal of Leinster, one of the earliest English proprietors in Ireland, who built a castle here, and made the town a free borough. By the Irish it was called Bally-Mac-Andom, signifying "Fitz-Anthony's town;" and from its situation at the head of the navigable channel of the Nore, it became at an early period a place of considerable trade and an important military station; it was surrounded with walls, and most of its buildings were castellated. The present town, in 1831, contained 527 houses, most of which are neatly built. ... Read MORE...
