I searched through the 1881-81 (there was no Newark city directory for 1880) looking for any women with the initials A.M.B. I only found one, Anna M. Bennett, widow of Uzal O. [Bennette], residing at 422 Plane Street in Newark. There are about fifty other women whose initials could be A.B. (i.e. their first names began with A, their last names began with B, and the directory did not give a middle initial).
Very truly yours,

Oh the things one finds:
Anna M. Pennington married Uzal Bennett (Bennette) on July 5, 1840, in Essex County New Jersey. Uzal was born in New Jersey in 1813 and died October 1849. He is burried in Newark. Anna appears to have been a long-suffering woman. In July 1841, Uzal was sued for seducing a young girl and ordered to pay$2500 to the girl's mother. It was a huge sum in 1841. We do not have a death date for Anna.
Isn't history fun!
