What bugged me with the name Matthew was yesterday I saw Luke, Mark and John Cockcroft in the Halifax area born around the same time.
Now that would make a good quartet of brothers named after the 4 apostles.
Only guesswork but you never know.
Another point I think if families were non conformist they tended to be more regular chapel attenders than some families who were C of E.
What I am meaning is non conformism was in relatively early days and I'm sure many people were nominally C of E but only went to church when really necessary so to make the effort to become a non conformist does suggest they would attend chapel regularly.
I hope that makes sense.
Edit Just found this.
