Damaged wall plate in 200 year old barn conversation

[Mark0395]

I have found a section of rot in the 3”x9” wall plate that was set in the cobble wall that spans about 3 rafters. What is the best solution to fix this?
By rot I mean completely disintegrated and 2 rafters have no support at the bottom end.
Also is there any way to tie down the wall plates as they are set in the outside edge on the walls, so over 100mm from the inside edge.

Might help if you post some photos.

I'd be thinking along the lines of prop rafters/joists - graft in a new piece - strapped to the existing via a piece of prepared, pre-drilled angle steel lapped well onto the existing, both sides.
