Hi,
Thank you for your message.
Do you have any more information that you could share? Do you have forenames/relationships to go with these surnames? Do you have any more specific dates that you could share such as birth/marriage/emigration dates? Do you know which member of the family emigrated? If so what do you know about their emigration?
Do you know what religious denomination the family were? You may be able to find information on the family in the parish church records. Most Catholic records are held locally, you could try writing to the parish priest for possible assistance. One website which may be helpful is the irishtimes website. Here they give an overview of what records are available in specific parishes. For Annaduff parish follow this link:

For information on Church of Ireland records go to http://www.ireland.anglican.org/index.php?do=information&id=63
You could also search for some record of them 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 the later Griffith's Valuation (1848-1864) found at http://www.askaboutireland.ie/griffith-valuation/
