Hi,
Please can anyone advise if writing to the 'Parish of Dunboe, Macosquin and Aghadowey' in search of a baptismal record, would cover all RC churches in Coleraine? Or should I write to all of them? Thank you.
The RC church in Coleraine covers all those civil parishes.
In addition, rootsireland (subscription) has baptisms up to 1900 for that parish.
