"The collection, consists of correspondence, genealogical notes, manuscripts, photographs, and published genealogies and diary.

Correspondence, 1923-1964, consists primarily of letters dealing with Estabrooks and related families, mostly New Brunswick although there is a small amount from various U.S. locations including Michigan, New York and Maine. There is a small amount of correspondence on subjects unrelated to genealogy such as Florence Estabrooks' writing of poetry and at least 1 play and include letters from Robert Cattley of the Classics Dept. at University of New Brunswick, Fredericton, N.B. and Ernest Crake or Croke of Mount Allison University, Sackville, N.B. concerning her play ""Alexander of Abounoteichus"", which was staged at Mount Allison University in the mid 1950s.

There are also two letters from the Federation of Progressive Societies and Individuals, of London, England in regard to her request for information about the organization in 1935 and the receipt of Florence's membership fee in February 1936. The organization whose president was Barbara Wootton and membership included Bertrand Russell and Aldous Huxley was formed in 1932 and appeared to be socialist in nature. The Honourary Secretary, Hugh Leakey, made a number of suggestions regarding setting up a discussion group and books to read including a book he referred to as the ""Manifesto"" and may have been ""The Communist Manifesto"". There is also a reference in the letter to Ms. Estabrooks to the Saint John Cooperative Commonwealth Federation, (C.C.F.) which later evolved into the New Democratic Party of Canada. There is also some correspondence related donations of copies of published genealogies to various institutions including the New England Historic Genealogy Society, Acadia University, Library of Congress (Washington, D.C.) , the National Library of Canada and the New York City Public Library.
