George Hamlin (1868-1923) was an American tenor. His daughter, Anna (1900-1988), was a soprano and voice instructor. The George and Anna Hamlin papers, dating from 1868 to 1983, document the careers of both vocalists through clippings, diaries, autograph books, programs, publicity materials, scores, photographs, and correspondence.

This collection contains writings and speeches; newspaper clippings; and pamphlets, programs and other printed material concerning political and civic groups, covering such topics as women's suffrage, women workers, women as jurors and city and state politics. Of particular interest to the study of the woman suffrage movement in Buffalo are membership lists of the Woman Workers Suffrage League (ca. 1908) and from the Buffalo Political Equality League (ca. 1905).
