Oh dear SPl the records will indeed give his admission date reason for admission and date of discharge or in his case death but there is a 100 year rule and you will nort be able to view the indoor relief book untill after January 1909.

My grt granny had a baby in the workhouse in 1904 and thats how i know

and she died in 1908 in 18 Leoville street just round the corner from your grt grt granda Sharkey.
Maybe you could phone PRONI and ask about viewing the indoor relief book for 1909 see if they would maybe bend the rules a bit.?
