Arabella M. Root (de l'Armitage) (1842-1904) was born in Montague City, Massachusetts, and died in Chicago, Illinois. She began her career as a schoolteacher. She married Henry L. Boylston, a clerk, in Lawrence, Massachusetts, in 1866. He passed away in 1879, and she married Robert de l'Armitage in New York in 1881. They subsequently moved to Chicago where he was a clerk and then a department manager for Chas. Gossage & Co., a large dry goods store. Arabella became a well-known singer, composer, lyricist, poet, and international philanthropist. She was the founder of the Drexel Boulevard Old Men's Social Club and a member of the Women's Relief Corps and the Progressive Health Club. She was invited to sing before both the Duke of Edinburgh and the Shah of Persia. In June 1886, her husband wrote a letter to Mary Baker Eddy on behalf of them both inquiring about books for those new to Christian Science. Based on the records available, we have found no further information concerning her involvement with Christian Science.
