Another location - King Cross Methodist. I don't know what the dates are, but I've a copy of the Grave plan, and I can see 3 mentions of the surname Baume - AA 6 and 7, plus Z 6. And I've just seen a note I made on a letter I received from King Cross - "Original Burial Book now at Halifax Archives". I'll have a look back at a RootsChat query I made on 12 September 2009, and see what came up there.
I'll, hopefully, be back!
