There is a memorial to FitzGibbon in the church at Stradbally, near Mountshannon.
"In memory of
John Charles Henry
Viscount Fitzgibbon,
only son of Richard 3rd Earl of Clare
and Lieutenant in the 8th Hussars
who was killed whilst gallantly
leading on his troop
in the glorious and memorable charge
of the Cavalry Light Brigade
at the battle of Balaclava
in the Crimea
on the 25th of October 1854.
Aged 24 years
A dutiful son
charitable, noble-minded, generous and brave.
He was respected and esteemed
by his brother officers,
honoured and loved by his soldiers,
adored by his family & friends,
where his gentle and mild influence
could only be equalled by his coolness and courage in the field.
This tablet is erected by his inconsolable parents
as a token of their affection
and their deep and everlasting sorrow
for his untimely fate.
'As the lot of heaven's favourites
is an early death
The Lord so loved and took him'
'Blessed be the name of the Lord'"
The phrase 'As the lot of heaven's favourites is an early death' is adapted from Lord Byron's poem Child Harold's Lament (Canto IV, 101): "Heaven gives its favourites — early death".
There was a particular personal connection between Byron and the Fitzgibbon family since the future John Fitzgibbon — 2nd Earl of Clare [uncle] was the "subject of a schoolboy crush" by the poet, four years his senior [Byron is said to have visited Mountshannon].
