It’s really common in folk magic types too, but I haven’t seen those written as calling on any other spirit than the devil or not at all, so I figured it didn’t answer the question. (That I can recall)
But yes, I’ve seen lots of bloodline curses- just not with demons for some reason. I can’t think of any reason that makes sense unless people as a whole are maturing and realizing that in most cases it’s really only the person who did us wrong that deserves punishment.
But idk, that’s a pretty out there theory based on what we see here on the forum alone!
I imagine there’s several who would do it. Focolar comes to mind, but I can’t confirm that. (Also can’t I spell their name without looking it up first)
