I have a home built in 1848. It has a stone foundation that has sunk and has
been sunk for several decades (I can tell this by the way the previous
owners who remolded in the 60's just made the baseboards wider to compensate
for the sagging floor). This morning I was walking the dogs and noticed a
section of the outside wall had fallen out. It looks like this has been a
trouble spot before because there are different types of mortar and cement
from previous repairs. I have some links to pictures and what I am hoping is
what I need to repair this, but I was wondering if anyone had any better
ideas or advice on how I can permanently fix this. I am by no means a mason,
and I think I am going to have a problem situating the stones back in where
they would actually do something structural rather than just lay in there.
Any suggestions?

I've read the whole thread, and looked at the pictures, and I'll join
the chorus here- that foundation is past any hope of spot repairs. It is
definitely not a DIY project. Short version- get a house moving company
in to support the place on jacks and cribbing, and get a foundation
contractor in there to demo those piles of rock loosely glued together,
clean up and square up the basement hole, and put in proper
footings/drainage and a modern foundation. Yes, it can be skinned with
the old fieldstone to may it look correct. Once the house is set back on
the new foundation, you can then figure out how to support the center
beam, and maybe pour a slab down there.

Hope your cashflow is good and your loan officer likes you- it ain't
gonna be cheap.
