I found Miss Van Rensselaer's book "The Livingston Family in America" (1949) of great help in researching my Livingston Family; see: http://www.robertsewell.ca/livingston.htmlhttp://www.robertsewell.ca/livingston.html
However, all I can find is that Miss Van Rensselaer was the daughter of John Jeremias Van Rensselaer and Florence Rutherford Taylor who married in 1864. It would appear she was born before 1870; and she is shown as "unmarried 1948." (see pages 216 and 327 of "The Livingston Family in America")
Does anyone have anything more on Miss Van Rensselaer, such as where she went to school, where she lived and when she died?
