In Boston, Bannister met his wife, Christiana Babcock Carteaux, who owned successful hair salons under the name Madame Carteaux. Together, they lived and worked with Lewis and Harriet Hayden, William Lloyd Garrison, Dr. John deGrasse, and Frederick Douglass, amongst other Abolitionist leaders. After the war, the Bannisters moved to Christiana's home state of Rhode Island. Their careers flourished. Edward was a co-founder of the Providence Art Club, winning acclaim, awards, and commissions. Christiana's successful salons backed all their endeavors, including founding a retirement home for women of color. They were as devoted to the community in Providence as they had been to the abolition of slavery.
