First of all, Thanks to Sue for her helpful suggestions about finding fathers in response to my queries.

Mary Ann Quayle married John Killip in Lonan 22/12/1866, her father being Paul Quayle, miner.
On the 1871 census, she is shown as being 38 yrs old and born i Maughold.
Does anyone have easy access to Maughold baptisms of circa 1833 ? I am currently working my way through the Lonan FHL films.
