Hi Dave,
On my records I have the following for -773 Private Jeremiah CAREY. Joined the 58th 29/03/1832
left Deptford on the 'Orator' 14/07/1843.
Arrived Sydney Aust. 14/12/1843.
Sailed to Auckland later in 1847 on the 'Pentongoee Bomangee' 12/07/1847.
On 25/05/56 he took his discharge, in Auckland.
It was a 'discharge to Pension'
In November 1858 the Rutlandshire Regiment of Foot Disbanded. A few of the soldiers of that Regiment returned to England with their Commanding Officer, Colonel Robert Henry Wynyard. So dont know what he did after his discharge.
All the best with your research of the 58th.
