This was the first church of the denomination among the Negroes of the District of Columbia. It was organized August 29, 1839, by Sampson White, a Negro, assisted by John Healy and S. P. Hill, white pastors of Baltimore, and Moses Clayton, a Negro minister, who was the founder and pastor of the first Negro Baptist church of Baltimore. The original members were William Bush, Eliza Bush, Lavinia Perry and Emily Coke. The accession of Sampson White and wife increased the membership to six. None of these had been members of any church in the District of Columbia. They held letters from churches elsewhere, and so were free to form a church of their own in this city. But the white Baptist church, which had worshipped at 19th and I Streets, Northwest, from the year of their organization, from 1802 to 1833, had many Negro members who worshipped at 19th and I Streets for six years before Sampson White organized his small congregation. These Negro members of the white church, being separated in worship from their white brethren, and having become sole owners of the house of worship which formerly they and the whites owned as members of the white church, wished to be organized as a separate body. This was refused. Sampson White, therefore, organized the First Negro Baptist Church of Washington, with persons not of the Washington white church, and thereby secured the recognition of his church by the leading white and Negro Baptists of Baltimore. In less than sixty days he had it in the oldest and best known white Baptist connection in America, the Philadelphia Baptist Association. This accomplished, Sampson White's little group received into their body all of the Negro members of the white church, except about twenty-three. These additional members made this a congregation ten times the size of the original body. This larger group, too, was in possession of the property at 19th and I Streets, at the time that the founders received them as members, and having been in possession of the property from the time it was sold to the Negro members of the First Baptist Church, white, these Negro Baptists, thereafter worshipping as the First Negro Baptist Church, insisted that the property was theirs, while the few colored members of the white church, who did not leave the parent body, claimed the property as belonging to them. This led to a law suit which lasted for years, but finally all the Negro members of the First Baptist Church, white, cast in their lot with the members at 19th and I Streets, and the trustees of the white church kindly released all claim in behalf of Negro members of that body, and rendered the deed clear.[15]
