This collection consists primarily of Conrad Wilson's genealogical research notes and ancestry charts for the Wicker and LaVake (or Levesque) families. Included with these materials is also research pertaining to several other related families, including the Wilson, Pearson, Haskell, Foster, Knowlton, Holman, Washburn, Johnson, Parker, Winslow, Robbins, and Lear families, among others. A copy of an unpublished memoir written by Conrad Wilson provides some additional Wilson family history alongside his life story. Also included are a number of letters from the family of Augusta (French) and Cassius Wicker, 1841-1903. The bulk of this correspondence was written by Augusta "Gussie" Carroll (French) Wicker to her husband Cassius "Cash" Milton Wicker between 1868 and her death in 1889. Other materials further represent Augusta Wicker, including a smaller number of letters written to her parents, 1856-1888, and estate documents, 1889-1903. After Augusta Wicker's death, there are other letters written to Cassius Wicker from his three young children, Henry Halladay Wicker (1876-1894), Lucy Southworth Wicker (1879-1943), and Cyrus French Wicker (1882-1968). Earlier letters from Augusta had included notes from the children and financial guardianship of Wicker's daughter, Lucy Southworth Wicker, is addressed in the estate papers. Other Wicker family members represented in this collection of correspondence include several residents of New Haven and North Ferrisburgh, Vermont. Among these are letters of: Cassius Wicker's parents, Maria Delight (Halladay) and Cyrus Washburn Wicker; his uncle, Charles Haskell Wicker (1816-1888); his cousins George (1847-1885) and Emma (Wood) Wicker (1855-1941); and other another cousin, Charles S. Wicker (1861-1915), also of Niagara Falls, New York.
