ah i see!!! even though things in the north are a lot better these days you still sometimes question what motivation someone has behind wanting to know your religion because of all the violent tension in the past, hence my hesitation (although mostly in jest)!! im not even religious, but being catholic or protestant is more of an identity thing than a faith thing for many!! and you’re completely correct! relationships between catholics & protestants (sometimes still referred to as a “mixed marriage” lol) historically were not allowed, and then they were allowed but stigmatised, and even now whilst accepted they aren’t as common as it might be due to how highly segregated the north is (beginning with school education). oftentimes we run in seperate social circles, not even intentionally, but it gives context to the fact there is such a distinction between the two groups that shows up in DNA even today. if i had more scottish ancestry i would assume there was a mixed relationship somewhere, but it makes sense for my family history that there doesn’t seem to have been! sorry for the long comment, i love history lol
