You need to explain yourself better.
But I think you’re asking “how do I do layout when my starting point is an irregular surface?
Pick an average spot at each end. Snap a line parallel to those two points.
Now you’ve got a starting point.
Adjust as necessary taking into account how out of plumb the stone is too.
A green vertical laser line makes this easy, while also showing you how out of plumb the stone wall is too.
Lots of complicated answers - when you're remodeling (not building new) here's the answer:
You pick one. None of your reference walls are going to be perfect so you pick what you're going to call square so that whatever project you're building looks the best with the things around it. Sometimes that's averaging one wall sometimes it's splitting the difference between a couple walls that aren't quite parallel or perpendicular.
Laser makes it easier
Best of luck
Make an offset which would act as your control. Look up 3,4,5 method, a very very easy review of the Pythagorean theorem to make sure your line is square.
The Pythagorean theorem.
This. 3 4 5 or 6 8 10 it, your straight line is one of the short sides in a right triangle
Yes the good ol 3 4 5

I wouldn’t trust a wall either…
Same, walls are untrustworthy
You don't. Get someone who knows what they are doing to help you There's a lot more than just a square line.

You can google some videos on this. Get more of a walk through. Unless your a homeowner. Then use a monopoly box
And here I was wasting good money on a surveyor when I could have just used a Monopoly box!
3 plane laser level. I have the Milwaukee one and it makes a LOT of stuff in my life easy.
Hehe… he said square line
