It’s more like Booker T’s granddaughter, Nettie Hancock Washington married Frederick Douglas’s great grandson, Frederick Douglas III.
This is their daughter Nettie Washington Douglas who merges the two families.
And her son Kenneth B. Morris.
They came out with a carefully worded statement against Umar Johnson regarding his claims of being related to Frederic Douglas. I think he most likely is. Many of these families had out-of-wedlock children that they kept secret that are coming out of the woodworks now because of DNA testing. The way that they worded this statement though leaves open the door of being a blood relative but not “directly descended”.
“The family of Frederick Douglass has received numerous inquiries about Umar Johnson questioning his relationship to Frederick Douglass. There have also been questions about the legitimacy of his PhD and handling of the donations he's received for a school he is promoting. We can tell you with 100% certainty that he is not a descendant of Frederick Douglass.
With that being said, Mr. Johnson is very careful not to bill himself as a "descendant", but he doesn't correct people when they refer to him in this way. He calls himself a "blood relative" which is a nebulous reference designed to make people think he is a descendant. We have researched his explanation of being a "blood relative" to the Great Abolitionist. Some of the information he provides is accurate, but an extremely important piece of his explanation, with regard to a documented relative of Frederick Douglass, is false. The information he recites correctly is from the public record so his knowledge of our family ancestry is far from definitive proof.
The official Douglass family tree is held in the archives at the Frederick Douglass National Historic Site in Washington, DC. Mr. Johnson's name is not on it.”
