Hi
Thank you for your message.
If you haven't already -You could try checking the land records called the Tithe Applotment Books (1823-38) http://titheapplotmentbooks.nationalarchives.ie/search/tab/home.jsp or the later Griffith's Valuation (1848-64) http://www.askaboutireland.ie/griffith-valuation/ or the Church of Latter Day Saints (LDS) https://familysearch.org/ for the various family members.
Civil registration records are available from the General Register Office (GRO). These start from 1864. You can access the website here: http://www.groireland.ie/research.htm
Valuations office in Dublin (http://www.valoff.ie) will have a record of the land registry from 1855 to modern times. This will assist in seeing what happened to any land the family may have owned (as it usually passed on to a relation).
