Hi Back,
I am no expert on fire blight, but know that disease pressure increases where 
trees lack much airflow and direct sun. Your tree just might be in too muck 
of a squeeze in that way. Also, some cultivars are more vulnerable to fire 
blight that others. 
Grafting was certainly worth a try. Did you graft to rootstock that has 
fireblight resistance? I've read (am trying it out, too) that some resistance 
may be conveyed via the rootstock to the fruiting wood. I've got some Geneva 
30 out back (no longer likely to be found on the market due to problems that 
don't concern me, and appears to be replaced by some verry promising 
rootstocks) and hope they will help when I graft Edward VII, as well as King 
David and Summer Rambo. 
Egremont Russet has quite a fan base; worth waiting to see...
