Hi Kelle,
Thanks for getting back to me. Yes I had been thinking it would have been a VERY old age to be getting married at!
Given these dates the main source of information will be church records as civil registration did not begin until 1864. Most Catholic records are held locally so you may need to write to the local parish priest for possible assistance. One website that you may find useful is the Irish Times where they give an overview of what records are available in specific parishes. It also shows you where copies of the records are available. For Kill/Rossmore parish, follow this link:
http://www.irishtimes.com/ancestor/fuses/rcparishmaps/index.cfm?fuseaction=showidrecords&CityCounty=Waterford&parish=Rossmore&churchid=1110
As you can see from the above link records for the early go back to 1797 so hopefully you may be able to find some information pertaining to Margaret there. Waterford Heritage and Genealogy centre have copies so you could contact them however a fee may apply. Here is their email: mnoc@iol.ie
You could also check for record of the family in the land records pertaining to Ireland in the 19th century. There are two:
The Tithe Applotment Books (1823-1838) found at http://titheapplotmentbooks.nationalarchives.ie/search/tab/home.jsp
and Griffith?s Valuation (1848-1864) found at http://www.askaboutireland.ie/griffith-valuation/
Please note that the land records are divided according to civil parishes. Kill town is part of Kilbarrymeaden civil parish:
http://www.irishtimes.com/ancestor/fuses/townlands/index.cfm?fuseaction=TownlandsInCivil&civilparishid=2397&civilparish=Kilbarrymeaden&citycounty=Waterford
If the the family were still in the area after 1864 all births, deaths, marriages would be recorded in civil records. Civil records are available from the General Register?s Office in Dublin. Here is their website:

You can search the indexes to these records up to 1958 online at:

Have you looked into her emigration much? Generally, more information was given at the port of arrival rather than the port of departure. The University of Woolongong has produced, on microfiche, a complete index and transcript of all information concerning immigrants of Irish origin recorded on ships' passenger lists between 1848 and 1867 for New South Wales. These are useful for finding out an exact place of origin as well as parents' names. The Public Record Office of Victoria has good online databases of settlers at www.prov.vic.gov.au Otherwise, other records may be found in the Colonial Office Papers of the UK National Archives, class reference CO 201. This class contains a wide variety of records, including petitions for assisted passages, emigrants' lists, records of emigrants on board ship, petitions from settlers for financial assistance and much more.

I hope some of this is helpful. Please be patient - as our programme has only begun to rollout across the island of Ireland and volunteers in some areas may not yet be organized.
Kind regards,
