Grace Whiting Mason, (1879-1971) was the youngest child of Albert and Lydia Mason and grew up on Corey Hill in the family home at 96 Summit Avenue (no longer standing). Her father was chief justice of the Massachusetts Superior Court from 1890 until his death in 1905. He is probably best remembered today as one of the judges in the Lizzie Borden murder trial of 1893.

Grace was part of the Brookline High School class of 1898 and the Historical Society has posted her collection of photographs of 14 fellow students. Their class (all but one graduated in 1898) was one of the first to attend the new high school that opened on Greenough Street in 1893. Grace was an 1898 winner of the J. Murray Kay Prize given to Brookline High School seniors by the Brookline Historical Publications Society (forerunner of the Historical Society) for historical research. Her essay was on "The Development of the Metropolitan Park System." After graduating from Brookline High, Grace attended Smith College, graduating in 1902. In 1904, she married Percy Sacret Young and moved with him to New Jersey where they raised four sons and four daughters.
