I don't think she really had a 'main talent'. She was barely seventeen when she died. That's hardly enough time for a person to discover a 'main talent'. She did what she enjoyed and these things are what her sisters did as well. She drew a lot and liked to color in their photographs and decorate photo albums. She liked playing with the dogs, reading, knitting, and playing tennis. If you had to think of one thing, maybe cheering people up.
