Bride Parish Register 1829-1848

Am I correct in assuming that the Bride Register dating from 1829 to 1848 is missing? I looked for a baptism about 1840 last night and Family Search do not have those records. The books prior, and after, those dates are there.
Looking for Robert Cowle. On his Lonan wedding certificate, April 1865 he names Robert Cowle, labourer, as his father. In all Census returns he states he is from Bride. I am aware that Francis believes that he is likely the son of one of the Caleys, as he is with them in 1851, aged 10. That’s the end of the line for me !!
