At last found my father's cousin, just tried name and day and month of birth, and there she was living where she still did in 1970. (Strange that I couldn't get her from the address). But her year of birth was transcribed as 1844 instead of 1914!
Then I wondered how many centenarians were on the register and searched with no name but just 1829 +/- 10 for birth year. And it came up with 168,418 results. Looking closer, the search includes many pages of people who have no birth year recorded (or maybe not transcribed).
Somehow the Guardian found there were only 111.

FindMyPast apparently provided the statistics to the Guardian according to the end of the article.

Obviously doesn't agree with their search engine results.
