The information I have is from family & church records mainly. I'm not related but they are fairly easy to trace.
Ringsend Presbyterian Church: Erected by Catherine Moffatt. In loving memory of her husband Thomas Moffatt, late of Cashel, died 22 September 1889 aged 42 years. Also their daughters Annie, Sarah, Ellen Jane and Margaret. Also the above named Catherine Moffatt, who died 1st April 1928 aged 80 years.
Forgot to add that I was told Thomas Moffat (c1804-1888) might have been married to a Hill, Cashel but I haven't verified that.
