Thank you for your message.
Unfortunately, it may be difficult to find record of Charles birth given the date. 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. 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. If you would like more information on these registers please check http://ireland.anglican.org/about/42 and http://www.nationalarchives.ie/.
Catholic church records in the areas that you have mentioned do not start until the 19th century. You can check the availability of Catholic records in Roscommon?s Catholic parishes here:
