HI Kenmure,
I would normally PM you the copy of the stone inscription but you need to post another couple of messages first before the site allows that..........
Here is the O Donnell stone inscription -
Erected by Mary Fullen in memory of her beloved husband John O Donnell, died 5th July 1876. Aged 40 years. And her two sons James, died 12th

? 1880. Aged 5 years. Francis, died 26th Feb 1864. Aged ? Years. The above named Mary Fullen, died 26th Sept 1877. Aged 44 years. er son John O Donnell, Died 15th July 1900. Aged 44 years.
If this does turn out to be your relations let me know and I will get a copy of the photograph to you
