Anderson & Hannaford remained together until the end of 1870.

He worked alone from 1871 until 1874.

He joined with Edwin Procter from 1874-1876.

He was again solo from 1876 until 1887 when two of his sons joined him in the firm Samuel Hannaford & Sons.

His retirement date is debated but the official announcement date is 1905.
