Looking for ancestor Edward Molloy , born 1804, Cavan.

Edward Molloy 1804-1854 from Cavan enlisted in 63rd Regiment of Foot in 1827 in Cavan, served in India and died as a policeman on the goldfields of Victoria Australia in Beechworth 17/8/1854. 

He married Mary Ann McConnen (India or Ireland?) and they had a daughter Mary Ann Molloy born Madras India. Mary Ann Molloy 1839/40 -1921 married Edward Daniel Sullivan (1836-1909)  in Tasmania.

I am searching for Edward Molloy's birthplace as I intend to visit Ireland later this year and want to visit the villages from whence my great great grandparents  came.

Born 1804, Killan, Cavan.  

I have a reference to father as Henry Molloy and mother Ann. 

Unfortunately this is not very detailed but it is all I have. I am hoping the Irish Birth records may provide more detail.
