Thank you for your query and posting this information. You will find the Roman Catholic Records for St Johns Kinsale by searching this website:
http://www.irishtimes.com/ancestor/browse/ Browse Roman Catholic Parish Maps-West Cork-Kinsale
From this you should be able to see what records still exist.
A quick search for 'Mellifontown' led to 'Mellefonttown Estate' Maybe a member of your family lived or worked here:

If you do not find what you are looking for we would recommend that you search emigration records. : Do you know much about their emigration? The dates, the reason why they left, who they may have travelled with?..etc..Generally more information was given at the port of arrival rather than the port of departure. If you knew which city they arrived at (e.g. Liverpool, New York, etc.), this could be a good place to find more information. -And perhaps even find out an exact place of origin.
