Hi
Thank you for your message.
Unfortunately the 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. Some registers for urban areas pre-dating 1800 may exist ? though often these can be fragmented- as there was an increased need in cities or larger towns to document the population. Please also note that the Church of Ireland was the official church of the country and therefore the bulk of information that does survive for earlier periods is often from these registers.
However, you can check for information about the frequency of the name in the mid-19th century and any other variant spellings of the name here: http://www.irishtimes.com/ancestor/surname/ to get an idea of the distribution of the name.
You may also wish to try any of the following for further assistance:
