Many thanks for your post to the Ireland Reaching Out message board.
Unfortunately, we do not deal with queries that are less than 100 years old due to privacy and data protection laws.
However, your best point of research would be to write to the Convent of Mercy.
In addition, you can do your own research using the Civil Registration Indexes (births to 1916, marriages to 1939 and deaths to 1965) in order to try to trace your ancestors.
The link for that website is here: www.irishgenealogy.ie It is the Civil Records that you will want to look at.
If you need further assistance, you can email me at: firstname.lastname@example.org
The best of luck with your research.
