The name "Jessica" does indeed show up in England about 50 years after this profile is dated, but to the best of our knowledge Shakespeare invented it.
The name Rebecca was used in England perhaps as early as this time, though this would be a very early use; a middle name, though, for this profile is very suspect, AND "Becky" is right out.
There are no sources given in this profile.
Where did this information come from?
And if it comes, as I suspect, from Web Trees Of Unsourced Invention, can we just detach it?
