Hi Kev
The 3319 Sir Claude Jullion met at the George Inn, High St Shirehampton Bristol
in 1954 under the Bristol Province of GLE. by 1976 they were meeting at the English Rose Broadlands Drive, Lawrence Western Bristol 4
By 1987 the lodge had closed.
Sadly I cant find a website for Bristol Province

All I can suggest is Write to their P G Sec, Bro A J Miller 11 Brixham Rd, Bedminster, Bristol BS3 5LH (address as in 2005 directory)
They might have something.
But at least you know the pub he drank in

ask your dad what colour the sash is, then I can tell you what degree he was
