I think that Polidor's GR contact has got wires seriously crossed. Just looking at the 1881 census seems to blow holes in the Stubbles/Shorley marriage. Florence born in Kensington registration district in the June quarter 1873 seems to be aged 7 in 1881 living in St George Hanover Square with her widowed mother Elizabeth Stubbles age 47 and siblings aged 23 (Jane b Reading) to 4. Elizabeth was born in Blandford Dorset, so seems to be the one that Carole found in 1871. There's a death of Richard Stubbles age 43 in St George Hanover Sq in March 1881.
There's an 1857 marriage in Reading of Richard Stubbles and Jane Kerley. There's an Elizabeth Kerly baptised in Blandford Forum in 1834, daughter of William and Jane. Elizabeth Stubbles eldest daughter was Jane. Elizabeth is consistently shown as born in Dorset in 1861-71-81 so I don't think there can be complications with second marriages
Any connection to Elizabeth Shorley born 1848 in Renhold escapes me! Florence's birth cert would prove or disprove my theory, which is just that - an untested theory.
Perhaps the GR contact can explain the logic. Does she have Florence's birth cert? Might there have been a Kerley/Sherley/Shorley bit of creative thinking? Doesn't explain the age/birthplace discrepancy though.
