William Shaphoff and his son are listed as a druggists or chemists in the Brooklyn City directories from 1884 - 1916. that’s as far as my research goes at this time. His mother Harriet moved in with him around 1890 after the death of his father. She is not listed as living with him in the 1900 Census.
