"Coffee and Lemon Cake" is a Substack post studying the beginning of the Purdie Family's experiences in Harlem and New York City at large via the Great Migration. It is a combination of oral history, family and archival research that traces the legacy of a Black American family in Harlem, the factors that contributed to their arrival there, and their reactions to the changes within the city as the family grows.
