extending celling joists help please

[kr5ai]

I have just taken out a ground floor fireplace from the 1930's. The chimney had no stack above it but only a vent going out through the wall to the left. However when I took it out i realised 3 celling joists supporting the upstairs bedroom floors were resting on top of the brick work of the fire place and these joists stoped around a centemeter from the brick cavity wall I have supported this with acrows for the time being. How can I attach the joists to the brick wall there is such littel space between the joist and wall? can I bolt another joist to the existing to make it longer? and then some how fix or can I get joist hangers and connect them straght to the brick work leaving a gap any help would be fantastic. please see my image of the joists

cut back the joists to fit a wall plate against the wall and rawlbolt it to the wall, fix the joists to the plate with joist hangers?

As above, and extend your old joists with new ones bolted alongside.

You can also extend joist by using, metal supports.
If you google, joist repairs, i'm sure you will find some info.
