Does anyone know Georgina Jenkin/Leenaert?

My sister disappeared about three years ago in France and we've been unable to locate her since. Interpol don't want to know. She was married in 1996 to a man called Jean-Marc Leenaert and divorced about 3 years later. She has a 12 year old daughter called Morgane, who lives with her grandmother. I don't think she's dead but I would like to know where she is and that she's happy. If you know her, please let me know.
