Hi Ian,
Now that you have given us all the details of JS's death registration (after my months of fruitless research!!) we're going to treat ourselves to a copy of his death certificate. We'd also like to get Elizabeth's of course but before I order it, I'd just like to check with you that I've got the info right.
You've posted all JS' details on the site - date, volume & page number etc. Maybe I haven't looked closely enough at your postings but the only info I can find that you've given about Elizabeth's death is the year - 1879. I've searched FreeBMD and found death record listings for two people of her name in Gateshead district in 1879. One died aged 46 so that can't be her. The other died aged 76 in the December quarter of that year so that looks like it could well be her. However, I'd really like to get my facts as straight as possible before ordering the certificates because from experience I know it's possible to get it wrong.
For example, on the FreeBMD site, as well as the relevant John Stephenson's death, (listed as you quite correctly say in Volume 24, on Page 97) they also list the death of another John Stephenson in the same volume but on page 95. Also from experience, I know that this might be a mistake by FreeBMD but equally, it may indeed be the death of someone else of the same name. On the FreeBMD site, for some reason, the search engine does not bring up death ages for records as early as 1844 so without your info, I wouldn't be able to tell which was the correct record for "our" John Stephenson. The ages on the two Elizabeth Stephenson death records seem to show that the 76-year-old must be the correct one but before I send for the certificate, do you reckon this is her?
