My Wife's Great Great Grandfather, Samuel McCarroll joined the 97th (earl of Ulster's) army regiment in Birr in 1840 - so I presume he may have up at Crinkhill Barracks, Birr. In 1841 he sailed with the Regiment from Cork, Ireland to the Ionian Islands in Greece and was stationed at Corfu until 1847 before being sent to Malta. In 1848 the Regiment was sent to Halifax, Nova Scotia, Canada to relieve the 23rd (Royal Welsh Fusiliers) Regiment of Foot.
Private Samuel McCarroll returned with the 97th Regiment of Foot to England in May 1853.
Records in 1861 show that he was stationed in Colchester, Essex, England
On searching the 1891 England, Wales & Scotland Census he is listed as living in Gillingham, Kent, England - an area where most of my and wife's family now live.
On the 1891 census it says that he was born in Ireland Rossbrew but I've been unable to find a town or village called Rossbrew, in Ireland. Other census records state his birth as Birr, King's Offaly), Ireland and the dates vary from 1822 to 1824 and 1826. Unfortunately I haven't been able to track down any details of his parents or siblings or any exact birth address.
