The papers consist of correspondence, writings, speeches, diaries, clippings, printed matter, and other papers related to descendants of Samuel Scoville, Sr. (1835-1902) and his wife Harriet Eliza Beecher (1838-1911). Materials document the activities of members of the Beecher, Gallaudet, Scoville, Trumbull, and Barry families. The bulk of the material relates to Alice Scoville Barry's research on Henry Ward Beecher, particularly on the 1875 adultery trial against Theodore Tilton and his wife Elizabeth Tilton. Her research notes include her opinions, book drafts, and correspondence with family members and close friends, including her brother Reverend Gurdon Trumbull Scoville (1904-1993). Additionally, the papers include materials relating to deaf education from Thomas Hopkins Gallaudet, Gallaudet genealogical information, writings, and family photographs. Also included are letters between Trumbull family members, biographical articles and obituaries of the Trumbull family, society applications with genealogical information, photographs, and newspaper clippings. Most of the Trumbull family correspondence is among Henry Clay Trumbull, Sally Ann Swan, James Hammond, Gurdon Trumbull, Sr., Gurdon Trumbull, Jr. and other family members. The collection also includes genealogical charts, sermons of Henry Ward Beecher and his father, Lyman Beecher, family correspondence, diaries of Harriet Eliza Beecher Scoville, and Samuel Scoville, Sr., and family photographs.
