Baptismal registers
The basic information provided in a baptismal register is the name of the child, the name of the father and the date of baptism. The mother’s name will usually be given as will a specific location. The occupation of the father and the date of birth of the child may also be provided. Roman Catholic registers will normally give the names of the sponsors of the child.
The Catholic baptism records for the diocese of Down and Connor, and to some extent the diocese of Dromore, contain valuable annotaions to baptismal records,
which often give details of the marriage of the indvidual concerned. Given the high levels of Irish emigration at this time, or indeed the movements of the population internally within Ireland, these annotations often refer to a marriage which took place in another country, or county within Ireland. Such records are an invaluable source for tracing Catholic ancestors. Researchers can maximise the research benefits of these records by using the Foundation's online pay-to-view baptisms and marriages search facility.

Might be worth asking the nice lady at St Peter and Pauls if they hold that sort of information
