Sarah Renou Bleg

Does anybody know anything about the nineteenth-century author Sarah Renou, or know of good resources for researching her? She shows up in my attempts to trace the (real but fairly subtle) influences of Lady Mary Shepherd on the thought of the day (Renou cites her, in fact, in this work), but I am having a hard time finding much on her that's useful (although most of her books and an old review or two of her works are available online). Nothing I can find even gives exact dates for her, or, indeed, much beyond a list of her books.
