A member of the uber-wealthy Carlyle Family in the fics of Brother Grimace, Miranda Carlyle is mentioned in A Path of Roses and Thorns by Andrea Nogura, who recounts her meeting with Miranda and four generations of her family as part a research projet on multi-generational families.

A strong, forceful woman of eighty-five (described as 'spry' by Andrea), with white hair (once a dark scarlet) and large green eyes, Miranda is stated as being from an incredibly proud and dignified family heritage, which she ridigly enforces upon the female members of the family. Her mindset is defined in the following statement:


'What you must understand, Miss Nogura, is that to be a Carlyle woman is not just being born into the position, but to understand what that entails; it is to uphold a tradition, a frame of mind, a way of life that has been passed down through the women of our line since before the birth of our nation. And so, the line of Carlyle endures today - the legacy of a great woman who had a vision, and a testament to the power of education – the lamp with which every Carlyle woman avails herself of, and in doing so, brings Majel Carlyle’s vision to pass.'


The grandmother of Forbes Carlyle and the great-grandmother of Julia Carlyle, Miranda lives in upstate New York, on an estate that is well away from the average person, and subsists entirely on the immense inherited wealth of the Carlyle Family. (The Carlyle family's wealth is estimated to be easily in the tens of billions of dollars.)
