From the history book Kansas Trails, published 1910:

“Alden N. Sullivan, the eldest son, is a member of the firm of Cyrus Sullivan & Son. He was born April 14, 1878, in Kechi township. His education was obtained in the public schools, Lewis Academy and the Wichita Commercial College. He first began work on the farm at home, and then entered commercial life as a traveling salesman for W. R. Case, cutlery, of Bradford, Pa., covering the territory of Kansas and Oklahoma. He continued this employment until 1908, when he engaged in the real estate business with his father. The offices of the firm are at No. 212 Anchorm Trust building. Alden N. Sullivan was married on December 28, 1904, to Miss Fannie Doratt, daughter of O. R. Doratt, of Wichita.
