Thanks to Noelle Lorraine Williams for sharing this name and New York Age obituary.
The New York Age called her “an energetic woman and a credit to her race”. She was one of the first public school teachers under James Baxter at the Colored School in Newark. She was listed as assistant to James Baxter with her sister Marcia.
Mrs. Brown helped organize the Sunday School at St. Philips Church and was an organist at St. Philips for many years.
She lived at 70 Warren Street and was part of the King Family, a Black family who had been in Newark for over 150 years at the time of her death. She was the daughter of Mary Thompson King.
The New York Age said she was involved in many charitable endeavors as well as business — she had dealt in real estate investments. Her husband John Brown was City Messenger under Mayor Haynes.
