The records for Dungloe RC are not available online and it appears baptismal records started in 1876. I was not able to locate a marriage record for Manus and Bridget. They were married pre-1864 (when civil registration started) and no church record is available. I see three civil records for children of Manus and Bridget: John Anthony 1864 Bridget (likely Delia) 1866 and Hanna 1869. The records can be found at the free site www.irishgenealogy.ie I would presume that James was born pre-1864 and maybe other children.
