Hi Robert,
Thank you for your message.
Unfortunately, reality of finding documentation pertaining to births/baptisms/marriages/deaths in Ireland prior to 1800 ? particularly in rural areas ? is that they simply may not exist. Also, as the Church of Ireland was the official church of the country the bulk of what does survive is often found in these registers. For more information on Church of Ireland registers check:
http://ireland.anglican.org/about/42 and http://www.nationalarchives.ie/.
Most Catholic records are still held at a local level, you can however use the Irish Times website to see what records are available in specific parishes. Unfortunately, records do not begin in Drumgoon until 1829:

Perhaps it may be an idea to contact Cavan Genealogy to see if they can assist you further, however a fee will apply. Here are their contact details:

I hope that you are able to confirm Cootehill as James and Susannah?s place of origin before your visit next year.
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,
