Hello Peter,
I realise it is a good many years since you posted your original message, which I have only just found, but just in case you are still out there....
I am descended from one of the Gorrick / Garrick families in Roscommon. My family are from Gaily, just outside Kockcroghery. The two versions of the name Garrick / Gorrick seem to be used interchangeably in the 19th century, mine are referred to under both versions in different records.
I spent some time looking into Garrick families in the area back in the 2000s to work out who was who, and did come across this couple Mathew Gorrick & Bridget Curly, in Kilteevan parish, but could not pin down a location for them. In Roscommon/Kilteevan I found 4 families in total; yours; another Mathew Gorrick of Newtown townland who married Honor Ratican in 1835 (and stayed there until he died in 1873); John Garrick of Clooncraff, who married Mary Killian in 1823, and John Garrick of Roscommon town (he ran a pub there) who married Mary Hanly in 1837.
I could not find an exact location for your family, and it seemed obvious that they must have emigrated, as there was no sign of them at the time of Griffiths's Valuation in the 1850s. I did find some possible references to them in Dewbsury in the 1850s but did not pursue it further.
I am not sure I can give you much more info on your family, but I am happy to share what I have in more detail if that would help.
Andrew Garrick
