Su, the directories aren't early enough ... that's been my issue all along, dagnabit!
I wrote to Sandringham (talk about a stretch!) to see if they held any historical staff records, thinking maybe Joseph might have worked there a while on his way to Kent. They referred me to Windsor, where all such records are kept. So, I guess I write Windsor again (have contacted them previously regarding OTHER brick wall).
Soldier on, troops! There's rum awaiting at the end of the hunt!
