In an exchange of emails on 9 February 2011, Sarah Ferguson asked Jeffrey Epstein for help with when a "wire" would be made to Columbia University.
It is unclear what the wire was.
Ferguson's email address has been redacted.
"I am embarrassed and sorry to ask you, as it is such a favour. What shall we do?" she said.
Responding the same day, Epstein said: "I need to speak to Andrew - don't worry".
Ferguson then replied by telling Epstein that Andrew was currently at the Royal Lodge in Windsor.
Both mentions of 'Andrew' appear to be references to Andrew Mountbatten-Windsor.
A reminder, simply being mentioned in the records is not a sign of wrongdoing.
In an interview with the Evening Standard on 7 March 2011, Ferguson apologised for accepting £15,000 from Epstein.
"I would never have anything to do with Jeffrey Epstein ever again. I abhor paedophilia and any sexual abuse of children. It was a gigantic error of judgment."
