Skiing Whymper couloir - Aiguille Verte

Please, I am looking for informations about first female ski descent of Whymper couloir (Aiguille Verte) and/or other women who skied its. I got one answer from Office de Haute Montagne Chamonix that the first women who skied Whymper couloir is Marie-Jo Vallencant (in July 1973 with Patrick Vallencant and Ansleme Baud). However in Patrick Vallencant’s autobiography http://www.bivouak.net/articles/Patrick_Vallencant_67.php?id_article=67&id_sport=1 he only mentions skiing this with Anselme. I don´t know what is correct?

According to « Les alpes du nord a skis » by Anselme Baud (Denoel editions), the day of the second descent in jully 73 by Anselme Baud and Patrick Vallençant, Marie Jo Vallençant started the climb but had to stop at mid-ascent. She waited there and joined the guys for the rest of the descent…
I don’t know about first female descent but nowadays the Whymper seems to be skied by dozens of people every year…
