The Walker Family Papers (WA MSS 501) consist of drafts or copies of letters written by Elkanah Walker during the years 1839-54. Many of the letters are unsigned and unfinished. The collection also includes letters written to Elkanah and Mary Richardson Walker and a number of family papers. Among the papers is a typewritten copy of a diary of Mary Richardson Walker, covering the period June 10-December 31, 1838, as well as material concerning the Columbia Maternal Association. The latter consists of the Association's Constitution and minutes for the period September 3, 1838-June, 1842. The Constitution is written in a careful, copperplate hand, possibly Mary Richardson Walker's, and is evidently the Constitution as drawn up at the first meeting, when Mrs. Spalding was elected president, Mrs. Walker vice-president, and Mrs. Gray recording secretary. It is followed by the minutes of the first meeting, September 3, 1838, in Mrs. Walker's hand, and the records of the meetings she attended through August 26, 1840, and an account of the general meeting of June, 1842.
