[2] Knocklong was originally known as Druim Damhghaire, the Ridge of the Oxen, but takes its present title from Cnoc Luinge, the Hill of the Encampment.

[5] Another version says that there was once a lake from Emly village in County Tipperary to the hill of Knocklong, on which small boats or ships used to sail.

Hogan's colleagues from the Third Tipperary Brigade -- Seán Treacy, Dan Breen and Séumas Robinson—were joined by Ned Foley, JJ O'Brien, Ned O'Brien, Seán Lynch, and Jim Scanlon from the East Limerick Brigade, to organise Hogan's rescue.

Treacy and Breen were seriously wounded in the gun fight, two policemen (Sergeant Peter Wallace and Constable Michael Enright) died, but Hogan was rescued.

The village has seen many of its residents over the years succeed in winning titles with both their club Garryspillane, "The Bouncers", and with their colleges and county team Limerick.
