Hi There
That's my point though is that it's legend, not fact.
IF she was brought to England ages 6 weeks old, then that's 1841, 1851 & 1861 census that she's missing from.
Just say the 'legend' is true ~ who brought her ?
Is / Was there an implication that she could have been orphaned / adopted, that leads to a whole avenue of other possible names that she could have gone by.
Could she have been married and widowed before her 1861 marriage, some didn't note it on a subsequent marriage cert ?!
I'm just trying to come up with ideas as to why, if the family story is to have merit, how is she missing from so many census'.
Hey, there could be a very simple explanation
