Our Fragmented Family Tree: Broken Roots, and Buried Truth in the World We Live In is a deeply researched examination of African American genealogy, Black family history, and ancestral identity. In this work, David A. Geiger documents how slavery, segregation, and systemic injustice disrupted African American family lineages and left generations disconnected from their roots.

Through extensive genealogy research, the book traces African American ancestry using census records, death certificates, military service documents, DNA ethnicity estimates, and oral family history. Each chapter reveals how historical systems altered names, erased records, and separated families, while also highlighting resilience, faith, education, and survival across generations.
