hi again,
My grandmothers family were mckennas and roman catholic they lived in same area at same time. Just a thought for you St josephs roman catholic church is on Armstrong Road, Newcastle Upon Tyne, NE4 area. You could write to the bishop and priest and request information directly from them. They allowed me so I'm sure that wont be a problem for you. good luck I will still have alook though for you. St James Church is Church of England so it's unlikely he would be buried there. St johns cemetry seems the more likely and catholics could be buried there in consecrated ground.
