Oh right. That was a record I had found ages ago. But the good news is that I have managed to find her! I was looking at her in 1851 and at the side, there were suggestions of other records, including one for an Elizabeth Anthony in 1901, married to Albert,. I then checked for a marriage and found one, in St Pancras in 1878 and theparish records show her to have father Samuel which is right. Just got Caroline to find now as well as Elizabeth in the missing years.
