More fun under the floor. Thankfully hasn't gone through the entire joist but does run the length of it. Hopefully sistering the whole thing sides will hold for another 130 years, rather than smashing the hearth out and lifting the floor.
I was always told that horizontal splits in timber joist are nothing to worry about (don't quote me if it falls down) - I wouldn't personally do anything but I'm architectural not structural
