Hi Paul.
I went to Cosgrove Church again this morning to see if I could pin point
any graves for the grandparents also to no avail.
The problem with the Parish Registers at the N.R.O. and Library, they only
hold up to 1877 for Burials so if Thomas died around that time we are okay,
if not maybe getting in touch with the Church maybe a good idea.
I went to the Library this afternoon and the Local Studies area was closed

.
It seems to be constantly closing without warning and if you telephone to the
Library itself you get a call centre who then call the Library and most of the
time they say they are engaged and could you call back later.

I will try again later for you.
Sandy
