Morris of Ballyea

My Great Grandmother Rita Morris was baptised on 2 Jul 1863, parents Patrick Morris and Mary Ann Roughan. Her name in the register is Bridget. Her daughter Bridget Rita (my grandmother) was also called Rita throughout her life. I am hoping to find any information on Patrick Morris and Mary Ann Roughan, especially their marriage.

I think that they would have been married around 1850 as there appears to be a son, Michael, born around 1850 (no baptism found for him). All other children were baptised at Ballyea from 1855 to 1863 in order Patrick, Margaret, William and Bridget (Rita).

Any help would be great!
