John Richardson (1790–1858) was Mayor of Swansea in 1844-45. His eldest son, John Crow Richardson (1810–1884), was Mayor in 1860-61, and his youngest son, Jeremiah Clark Richardson (1822–1906), was Mayor in 1864-65.

John Richardson was born in South Shields, Co. Durham, in 1790, and moved to Swansea c.1818. He was a prominent merchant and shipbuilder, and served in various public capacities including Alderman, Mayor, of Swansea Harbour trustee, and Feoffee of the Swansea Grammar School. He was also well known as a benefactor of charitable institutions.

In 1809 John married Elizabeth Clarke, from North Shields, and had twelve children, the oldest being John Crow Richardson (1810–1884). John Crow followed his father into shipping and trade, as well as playing a prominent public role. Like his father, he was an alderman, Mayor of Swansea, and a long-standing Swansea Harbour trustee. Also like his father, he was a supporter of various charitable causes, and was responsible for the building of a number of churches in Swansea. He also served in the 3rd Glamorgan Volunteer Rifles and became Acting Commandant after the death of founder, Lewis Llewelyn Dillwyn

At the behest of his brother-in-law, George Grant Francis, another former mayor, John Crown Richardson paid for and donated to the city a charter chest decorated with seals which had been designed by Francis. Francis's and Richardson's seals appear on the chest, along with those of the city, kings of England and lords of Gower.

Jeremiah Clark Richardson (1822–1906) was the third member of the family to be Mayor of Swansea, was a JP, Harbour Master, and held a captaincy in the 3rd Glamorgan Volunteer Rifles.

The Richardsons of Swansea claimed descent from the Richardsons of County Durham and used their arms.
