Certain localities in Ireland were given this name, probably because "in old times some tenant held them free of direct rent, as a reward for some signal service, or on condition of fulfilling some special duty".

[3] Local tradition has it that a king lived in the castle, and offered his daughter's hand to whoever could rid the land of a gigantic boar and sow that uprooted crops and killed anyone they met.

The title Baron of Loughmoe is an Irish feudal barony, and was possibly raised to a Jacobite peerage in 1690 while King James II of England was in exile.

In 1858 in Loughmore, two local men, Daniel and William Cormack, were executed for the murder of John Ellis, a land agent from Kilrush, near Templemore, County Tipperary.

The brothers William and Daniel Cormack were arrested and convicted at Nenagh Assizes in March 1858, largely, it was felt at the time, on the evidence of an informer – "a villainous character" – who was widely believed to have been part of the murder plot.

Daniel's and William's remains were ceremonially removed from Nenagh Gaol and brought back to Loughmore with two hearses drawn by plumed horses, followed by huge crowds.

After the procession arrived in the village, the Cormack brothers were buried in a mausoleum in the churchyard where people still go to see the original oak coffins and the inscription proclaiming their innocence.

On one side of the mausoleum is inscribed: By the Irish Race in memory of the brothers DANIEL and WILLIAM CORMACK who for the murder of a land agent named ELLIS were hanged at NENAGH after solemn protestation by each on the scaffold of absolute and entire innocence of that crime, the 11th day of May 1858.

The tragedy of the brothers occurred through false testimony procured through GOLD and terror, the action in their trial of JUDGE KEOGH, a man who considered personally, politically, religiously and officially was one of the monsters of mankind, and the verdict of a prejudiced, partisan packed perjured jury.

Clear proof of the innocence of the brothers afforded by ARCHBISHOP LEAHY to the VICEROY of the day but he nevertheless gratified the appetite of a bigoted, exterminating and ascendancy caste by a judicial murder of the kind which lives bitterly and perpetually in a nation’s remembrance.

In the morning a solemn REQUIEM OFFICE and HIGH MASS were celebrated in the Parish Church, Nenagh, Canon McMahon presiding, and an immense number of Killaloe priests being in the choir.

At Loughmore, the pastor preached a funeral oration and assisted by priests from IRELAND, ENGLAND, AMERICA and AUSTRALIA, officiated at the placing of the remains here to rest in peace and honour until the day of their vindication by Jesus Christ before the whole human race in the Valley of Josophat.
