Why should I become a member?

Membership in the Sons and Daughters of the United States Middle Passage (SDUSMP) honors and preserves the legacy of your ancestor(s).  For around two hundred and fifty years, your ancestors endured the cruelties of slavery to emerge resilient in their pursuit of freedom and equality.  We applaud their bravery, strength, great faith, skill, ingenuity, undying hope, and persistence.  We believe they were driven by the hopes for their own freedom and the freedom of their descendants.  We are the freedom they dreamed about and we celebrate each other.  

We, their descendants, also owe them our very lives.  As a member of SDUSMP, through participation in the Society’s various programs and activities, you can honor this legacy by actively supporting historic preservation, promotion of education, and patriotic activities.

SDUSMP provides the opportunity to:

  • educate others about the contributions of enslaved people, the institution of slavery in the United States, and the current day effects of slavery;
  • connect to other people who have done the work of identifying their enslaved ancestors and who are passionate about helping others;
  • participate in the preservation of their legacy by helping us form the “Book of the Remembered”, a major project.  It is a collection of the names, stories, and other historic information about all of our ancestors who were enslaved;  
  • honor the patriotism of our ancestors and their descendants;
  • honor and preserve the forced sacrifice legacy of our ancestors;
  • network with members of your community, nation, and worldwide;

How does one trace their ancestry to an enslaved person?

Starting with yourself, document your parents, grandparents, their parents, and so on, going back as far as you can, through interviews with parents and older relatives.  You can use this document to record your progress. Using online genealogical databases, such as, and, locate documentation, such as census data, and birth, death and marriage certificates, substantiating dates for each generation.  Some people will be able to use family histories, ship manifests, slave narratives, wills, newspaper articles, and other information.  These are all acceptable as documentation to prove lineage.  Consider joining genealogical societies like the Afro-American Genealogical Historical Society to help with your research.

Use our worksheet to help document your ancestry.  All birth dates shall be supported by birth certificates or other evidence, naming both parents’ and child’s full date of birth.  Proof must clearly tie each generation to the preceding one.  Acceptable proof includes birth and death certificates, wills, probate records, Bible records, church records, court records,  and census records.  Please identify all family members that served in the United States military, documenting the branch, dates of service, capacity, and name of the war.
