What’s in a Name?

We are often asked, “What is the Middle Passage?”

The Middle Passage was the stage of the triangular trade in which millions of people from Africa were shipped to the New World as part of the Atlantic slave trade. “The triangular trade system was so named because of the route it took.  The ships embarked from European ports, and stopped in Africa to gather captives.  After this, they set out for the “New World” (North America, South America, and the Caribbean) to deliver their kidnapped victims, and then returned to the point of origin. The transport conditions were horrendous and millions of enslaved people died on these voyages.  


Sons and Daughters of the United States Middle Passage (SDUSMP) is a lineage society dedicated to the memory of our freed and enslaved ancestors and to the education and historic preservation of the artifacts and landmarks of slavery in the United States of America and its economic, psychological, and cultural impact on today’s society. Lest we forget.  SDUSMP is a non-profit, charitable 501(c)3 organization. 


The objectives of the organization are Historical, Educational, Memorial, and Patriotic: 

  • To promote the connection of descendants of the Forced American Heroes, the enslaved people of African descent, to their ancestors through genealogy research;  
  • To proclaim, through education, the role played by the Africans forcibly brought to United States in creating our nation, including their endurance of the cruelties of American slavery, their resourceful intellect; their extraordinarily strong will and spirit, and their connections to their descendants who have gone on to make our country greater. We want to especially commemorate the connections to all military soldiers; 
  • To educate the nation and world about the contribution of the enslaved and their descendants;
  • To cherish and to strengthen the family ties among the members of the SDUSMP; and
  • To collect, protect, and preserve the materials necessary for a complete history of slavery, and to mark the places of the sacrifice of these men, women, and children; our ancestors.  This is including, but not limited to, historically significant sites such as churches, battle sites, freedom trails, grave sites, plantations, and museums.  Lest we forget.
