Hi,
Thank you for your message. I hope that someone recognises the names you have mentioned and makes a connection with you.
Have you tried looking in the 1901/1911 census records to see if there were any McMahons still in the area at the time? You can search these here: http://www.census.nationalarchives.ie/search/
You could also try looking in Church records for more information on the family. Most Catholic records are held locally so it may be an idea to write to the local parish priest for possible assistance. One website which you may find useful is the Irish Times. Here they give an overview of what records are available in specific parishes. For Tomgraney/Killoe follow this link:
http://www.irishtimes.com/ancestor/fuses/rcparishmaps/index.cfm?fuseaction=showidrecords&CityCounty=Clare&parish=Kilnoe&churchid=764
For Church of Ireland records check http://ireland.anglican.org/about/42 and http://www.nationalarchives.ie/.
Some records from the 19th century can also be found online at www.familysearch.org
Civil registration began in Ireland in 1864, so if Catherine died after this year there will be a record of her death in the General Registers Office in Dublin. Here is their website:

You can search the indexes to these registers here:

If her death was before this time, you may be able to find her burial record in the local parish.
Have you tried looking for the family in either of 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/
It may also be a good idea to look into Michael and Patrick?s emigration as sometimes more information was given at the port of arrival rather than that 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.
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.
