Conjoined twin Faith Williams has died on Christmas Day, 23 days after the death of her sister.
Faith and sister Hope were joined at the chest when they were born on 26 November. Hope died in an operation to separate them on 2 December.
Faith's mother Laura, 18, from Shrewsbury, Shropshire, and father Aled, from Anglesey, were at her bedside when she died.
Great Ormond Street Hospital said it was a sad but not unexpected outcome.
