Where would one look for such records available on microfilm from outside of Northern Ireland?

In particular, I'm looking for Church of Ireland record(s) for my ancestors who had resided in Derrylard and primarily in Cloncore (circa 1855 - 1890). I do have baptism records for children born between 1865 to 1877, however, I'm looking for earlier entries and marriage of parents.

Thank you in advance.
