There is a possible sexual affair and certainly a flirtatious affair with Maria Cosway, a married English woman whose husband was apparently quite forbearing. It is simply not known whether that relationship was consummated but it appears to have been over just before the arrival of 14-year-old Sally Hemings in Paris. Certainly, Jefferson was quite smitten with Cosway and she evidently with him until the relationship cooled.
That is correct I forgot about that. Other than these two the others are rumors with no evidence.
