I have entered alternative names for the family on Ancestry
In 1851 she is actually enumerated with no birth place rather than Limehouse so only the 1871 states that
Have you seen the actual marriage from the PRs? it wil not give a great deal but may have a snippet about her Parish or place , certainly worth a try if you haven't already
