I've come to the party late on this one.
However I can tell you that the Laura E CALLOW, Sister, 23, born Souldern Oxfordshire on the 1901 census is almost certainly in fact Laura Ellen TEBBY, another daughter of William and Ellen (formerly Robins) TEBBY. The very same William shown in a post above above living with his widowed daughter Annie M KEMSLEY with Agnes A GIBBS as a visitor on the 1901 census. The 1881 census shows a 3 year old Laura Ellen TEBBY, born in Souldern, living with her parents and brothers "near station Aynho."
I would therefore be very inclined to think that "Annie Elizabeth" is probably Hannah Elizabeth as this is additional evidence given that we know Annie M KEMSLEY (formerly TEBBY) is living in Croydon with her widowed father William at this time.
Hope this helps...
