The Natural History of the Cornelia Warren Estate: Camp Cedar Hill, Girl Scouts of Eastern North America by Lesley Sneddon Now Available! Camp Cedar Hill is a portion of the former estate of Cornelia Warren . In keeping with her desire to maintain the land for public benefit, Ms. Warren wished to carry this tradition beyond her life by stating so in her will. After her death, the Trustees of Cedar Hill deeded five parcels of the estate among several beneficiaries, including the Massachusetts Girl Scouts (now the Girl Scouts of Eastern Massachusetts). To this day, Cornelia Warren’s legacy of philanthropy and social welfare continue to benefit the residents of Waltham and beyond.
