Do you mean the. Volume number and page number were the same on both entries? I f so I'd say it was one death registration but her name had been given as X otherwise known as Y. Possible she had separated or divorced and reverted to using her maiden name ?
I ordered a death certificate of a woman with surname beginning with N.
When it arrived, her surname began with B, but was the correct person, who had remarried after being widowed.
Certificates now have a section for the informant to state any other names the person had used and the index will record each of these surnames, but they are all the same person and same certificate.
