does Robert Fox appear as her father's name and a Robert Fox sign as a witness? If only as the name of her father, it does not mean that he was there or even that he was still alive.
Who were the witnesses? This info may help us trace Elizabeth before her marriage.
What address is given for her on the marriage cert? Have you looked for that address on the 1861 census?
