Jane,
Tradition was to marry in the bride’s church, after which she’d normally attend her husband’s. There is a marriage in Tubrid Church of Ireland on 10th June 1832 but this transcription says it was between Christopher Noble (not John) and Rebecca Irvine.

The marriage record indicates that Christopher lived in the parish of Drumkeeran (Kesh is in Magherculmoney parish). So Jane's 1834 baptism (and that of any siblings) may be in Drumkeeran’s records. They start in 1801 but I don’t think they are on-line anywhere yet. There is a copy in PRONI (the public record office) in Belfast.
Drumkeeran is the next parish to the north of Magheraculmoney. See map:

Griffiths Valuation for 1862 lists 1 Christopher Noble in Drumkeeran. He had plot 8c in Corlave. That was a labourer’s cottage on John Boyd’s farm. (On the modern Formil Rd between Letterkeen and Rockstown). There was a William Noble living nearby on 7b, another labourer’s cottage. Perhaps a relation. Christopher was deleted from those records in 1869. I don’t see death records for him or Rebecca. Did they emigrate?
