Thanks, solidrock.
Sorry, everyone, I obviously wasn't clear what I was asking for.
I've got my Robert William & Elizabeth Baker on the censuses and their bmds on the GRO indexes. The probate entry for Robert confirms it's the right person. I have their descendants censuses/bmds/1939 register too.
There is a burial in Bury St Edmunds for a Robert William Baker on the NBI*, 25 Jan 1890, which looks likely to be him.
There is a death of an Elizabeth Baker Q3 1887, Ipswich Registration District and what may be a corresponding burial on the NBI in Bury St Edmunds 27 Sep 1887.
I am trying to confirm that that burial is my Elizabeth, so I can kill her off.
The graves are not on findagrave.com nor on gravestonephotos.com, nor on deceasedonline.com
If someone is going to a branch of the Suffolk Records Office (probably the Bury St Edmunds RO), I would be grateful if you could see if you can find these entries in a burial register and let me know the Abode and Occupation shown. If it's a municipal cemetery, the register may also show grave numbers, which would also be useful, as if they're in the same grave, that would be conclusive they were man and wife.
If I can tie them in with each other through abode, occupation or grave number, I can then draw a line under that branch.
