Dathai I have found them in Workhouse records for 1888.
Denis McGrath aged 11, child of a Baker who is also in the workhouse. He is discharged October 1888 " to Uncle"
Father is Edward McGrath aged 40, a widower, Baker of 46 Nicholas street. He died there 21 Sept 1888.
There is a note to say he has three children in the workhouse - I'll look back see if I can find them later. (at work at the mo)
