Mary and the African American church

[RJNorton]

While researching this I came upon a web page with some colorized images I do not recall seeing before:

I am quite skeptical about Mary Coakley at this point. Does anyone know where in Keckly's book there is a reference to Mary Lincoln employing other seamstresses in addition to Keckly? I would be interested in reading Keckly's exact words on this topic (apparently there is no mention of a Mary Coakley). Thanks.
