I meant to post way back... here is Sr. Marie-Angélique of Jesus (1893-1919) who was at the Carmel in Pontoise, France. She is similar to Blessed Elizabeth in that she was an excellent pianist & spent 5 years in Carmel, dying at the age of 26. I am not sure if there is a process going for her canonization, but I am guessing there must be. She is often named with the other great French Discalced Carmelite Nuns, like in this painting of a vision Madame Acarie (Blessed Marie of the Incarnation
