Hi Roger,
I know lots of questions, probably a bit more confusing because both father and son are called James Shaughnessy.
We were given Barrettstown as the location for James, i didn't know about the Waterstown connection until i saw your reply. Could they have been buried in Brides Church Cemetry? Would there be a listing for that graveyard somewhere, its quite old, i don't think it would be safe to go take a look round, i checked it out on the graveyards website and its down as being a closed graveyard.
Maybe if i give you what i have from James and Alicia's Marriage Certificate that would help, sometimes name associations are a good way to trace people as well as dates.
Marriage Date: 26/02/1865
Place: Caragh, Naas, Kildare.
(also for caragh have - Kildare & Leighlin -- alternative parish name Downings)
Name's: Jame's Shaughnessy (Jr) - Alicia Power.
Jame's profession: Labourer.
Jame's is from Barretstown.
Alicia is from Waterstown.
Fathers names: James Shaughnessy (Snr) is a Labourer - William Power is a farmer.
Two wittnesses for the wedding: John Smullen and Mary Byrne.
They had Three childern;
Bridget Maria Shaughnessy, born 15 September 1865, we think she died soon after but can't be sure, can't find a death certificate. I did manage to find some information about a baptism for 17 of September of that same year.
Catherine Shaughnessy (Kate), born 1872, died 22/09/1951
Patrick Shaughnessy (my great grandfather) born 27/01/1868, died 29/06/1946
Both Catherine and Patrick are buried together out in Glasnevin With his son and daughter-inlaw.
Catherine never married but continued to live with Patrick and help to raise his childern when his wife (Mary Shea) died in 1910.
Hope the above is a bit more helpful to you.
Many thanks for all your help Roger, i really appreciate it.
