Update - I have found a marriage record for Jeremiah Ryan and Catherine Frewin. They were married in St Mary's parish, Limerick on 9 January 1827.
I also found 2 birth records. One is for George Ryan (son of Jeremiah Ryan and Catherine Frewen), he was baptised/christened in St Mary's parish on 26 July 1827. The other is Thomas Ryan (son of Patrick Ryan and Catherine Freuen) from Cully. He was baptised/christened in Newport parish, Tipperary on 1 November 1840.
Is Cully near Culley Rocks, Tipperary?
Does anyone have information about these people?
