Louise Françoise was born in Tournai on 1 June 1673[REF] while her parents, King Louis XIV and Françoise-Athénais de Rochechouart were on a military tour; her maternal aunt, the marquise de Thianges, was there also.
After the death of Mademoiselle de Tours, Madame de Montespan wrote to the duc du Maine: I do not speak to you of my grief, you are naturally too good not to have experienced it for yourself.
