Thanks Niel for your ideas, but the second Annie BRADFORD is born 1878. She would have been 12 in 1890. The death certificate for 10 month old Alice Mavis SHERDEN Apr 1891 (616/1891) lists her mother as Annie Maria KIRBY.
But perhaps I should order both the birth certificate for Alice Mavis SHERDEN (25572/1890) that should give me some idea who her mother is. Hopefully she'll be the informant which will eliminate the need for me to order the 1889 death certificate of, Annie M KIRBY (1413/1889) - Maybe I should order a transcription anyway.
I've just had a brain wave, perhaps Alice Mavis SHERDEN was born Dec 1889 and registered in 1890 (25572/1890) and like you said Annia Maria KIRBY may have died in child birth and her death registered in that year 1889 (1413/1889). I know it states on little Alice Mavis SHERDEN's death certificate Apr 1891 that she was 10 months. But obviously their sense of time was severely distorted back then.
