Sounds like she was a woman of letters. That used to be more of a thing, someone who corresponded a lot and had an influence on a lot of notable people, one person at a time. It seems that while she would have had a tremendous impact on the intellectual life of her time, it would have been all through personal relationships that wouldn't have left much of a trace when both parties died.

And we have no way of knowing that she'd have wanted it any other way - she clearly had the respect of the people who mattered to her.
