‘Carrick and Carrig are the names of nearly seventy townlands, villages and towns, and form the beginning of about 555 others; craig and creag are represented by the various forms Crag, Craig, Creg, &c., and these constitute or begin about 250 names; they mean primarily a rock, but they are sometimes applied to rocky island.
Carrigafoyle, an island in the Shannon, near Ballylongford, Kerry, with the remains of Carrigafoyle castle near the shore, the chief seat of the O’Conors Kerry, is called in the annals, Carraig-an-phoill, the rock of the hole; and it took its name from a deep hole in the river immediately under the castle.’

‘Sir William Pelham and the earl of Ormond set out early this year [1580] on a fresh campaign in Desmond’s territory; the first marching first to Limerick in the beginning of February, and the latter to Cork, and both forming a junction at the foot of Slieve Mis, near Tralee. They spared neither age nor sex in their march, and, owing to the state of desolation to which the country had been reduced, suffered not a little inconvenience themselves for want of provisions. They then marched northwards to destroy the castles still garrisoned by Desmond’s men, and first laid siege to the strong castle of Carrigafoyle (Carrig-an-phuill) situated in an islet in the Shannon, on the coast of Kerry. The Four Masters say that Pelham landed some heavy ordnance from Sir William Winter’s fleet, which arrived on the Irish coast about this time, and battered a portion of the castle, crushing some of the warders beneath the ruins; but other annalists make no mention of cannon landed from the ships.’

‘For the rebels it was a losing game all through. Pelham and Ormond took Desmond’s strongholds one by one. Carrigafoyle Castle on the south shore of the Shannon was his strongest fortress. It was valiantly defended by fifty Irishmen and nineteen Spaniards, commanded by Count Julio an Italian engineer: but after being by cannon until a breach was made, it was taken by storm about the 27th March. Without delay the whole garrison, including Julio with six Spaniards and some women, were hanged or put to the sword…A few days after the capture of this fortress the garrisons of some others of Desmond’s castles, including Askeaton, abandoned them, terrified by the fate of Carrigafoyle.’
