Hi,
An old post I know, so you might have found this already but just in case,
Marriage
England Roman Catholic Parish Marriages
05 Nov 1865 Parish: Rotherhithe, St Peter & Guardian Angels
Elizabetha CARROLL
Father: Edmondi CARROLL
Bride
Joannem BUTLER
Father: Jacob BUTLERI
Diocese: Southwark
This also shows that Elizabeth's father was Edward not John.
Looking at the 1861 Daniel DRISCOLL census both Ellen and Eliza were born in Ireland, if they were Elizabeth's sisters maybe she was born there too. Could Eliza be Elizabeth?
Regards,
Daisy
