Thanks Bob

I agree this must be the Annie Delores Brain that was born 1908 with possibly a slip up by the enumerator. Sometimes a person is shown on the census with a different name, it usually being a "chosen" preferred name, but not for a second name.
I think the birth reg. as per Slowhands details is probably her:

Name: Annie Delores Brain
Year of Registration: 1908
Quarter of Registration: Jan-Feb-Mar
District: Westbury On Severn
County: Gloucestershire
Volume: 6a
Page: 288
