I am hoping that under the heading "Occupation" it
may say "wife of Matthew Ward". As she was married, I believe this is what generally happened.

Of course this would depend on whether or not the informant knew she was the wife of Matthew Ward.

If she died at the infirmary or elsewhere the informant would not be Matthew I suppose, unless he happened to be present.
I suppose it is possible that now the GRO will not issue the certificate if the occupation column is blank? We could miss out of the correct certificate! Panic!
We'll just have to wait and see, and keep our fingers crossed.
