I think your Catherine could be a younger sister to my 3X great-grandfather Philip Quayle. His parents were a William Quayle and Catherine Cubbon.see Family Group Sheet below. The pattern of the christenings in the parishes of Marown and Braddan seem similar. However I do need to check this info from the parish registers rather than just the IGI. I could do with a will for William Quayle or Catherine Cubbon to confirm the connection. I do have a larger list of Quayle descendents of Philip Quayle and his wife Jane Taggart.
