The personal papers of Helen Danner and her parents Frederick Baxter Danner (1907-1979) and Elizabeth Neill Danner (1907-1991). Frederick Danner grew up in Mount Vernon, N.Y., and graduated from the Massachusetts Institute of Technology. He was then employed by AT&T's Long Lines Division for 42 years. Elizabeth Neill was born in Milwaukee. She attended Sweet Briar College in Virginia. She married Frederick Danner in 1935. They moved to Litchfield in the early 1970s. Helen Danner's papers include correspondence related to her attendance at Carleton College and her travels in Europe during that time and other documents. Her parents' papers include an extensive run of their personal income tax returns, along with correspondence, deeds, passports, World War I and World War II documents, scrapbooks, and other materials. There are genealogical records relating to both the Danner and Neill lineages. The collection also contains photographs. Some of the documents date to the 1800s, including a scrapbook, a small leather-bound account book, publications, a newspaper account of Abraham Lincoln's assassination, and a family record torn from an 1832 Bible.

An inventory is available for most of the collection.
