Renée Lennox is supposedly the illegitimate daughter of Jacqueline de Mezieres and Charles Lennox, 1st Duke of Richmond, and the mother by her cousin Charles Beauclerk, 2nd Duke of St Albans of an illegitimate daughter Diane Beauclerk-Lennox or de Beauclerk-Lennox. Nothing more is known about Renée, but she is found in many Internet genealogies and biographies, including in the Wikipedia article of Charles Beauclerk, 2nd Duke of St Albans, though without citing any sources.
However the genealogy of her mother's ancestors, found here and the genealogy of her daughter's descendants, here are both by the same person and have some defects. Much of the important information can't seem to be verified and neither cite any primary or even secondary sources.
Given this, the existence of all three women is questionable unless some credible information can be found.
