Anything is possible, but her birth cert. is registered in Aisholt with only her mother's name Emma, and the Parish in Enmore has made the entry with Emma Harding as mother, but the entry on the census, both 1881 Emily is 22, if I recall it properly, and the 1861 Emily is 12.
This would be my great grandmother. I have the marriage cert for Emily and John Alford. George Harding is listed as the father. Could this be George Charles Harding?
