1836 Born in Ludlow in 1836, of a minor landowning family.
In 1851 at age 15, he was sent to Wolverhampton to be apprenticed to Edward
Perry at the Jeddo Works of Wolverhampton as a japanner (metal lacquerer).
In 1859, at the age of 23, he bought Edward Perry and Co and possible Richard
Perry, Sons & Co - two existing tinplate manufacturers and set up on
his own as John
Marston Ltd, making any and every sort of domestic article. Another
source says: When his apprenticeship ended he purchased Daniel Smith Lester's
japanning business at Bilston which had amalgamated with Fred Walton and
Co and Thurston and Co. John was just 23 years old. 
In 1887 the first Sunbeam bicycle had been turned out at the works.
He gave William Newill a partnership, and the company began to change direction
from making pots and pans to engineering.
1888 The Paul Street works first became known as Sunbeamland in 1888 and
Thomas Cureton, joined the company as an apprentice.
Marston disapproved of motorcycles, which he thought were dangerous. This did not stop him making thousands of them. But he never rode one, and nor did he ever drive a car. Nearly
all his life he was a dedicated cyclist, most often using a tricycle. He was a successful businessman, and an apparent harsh employer. Workers who made a mistake at his factory
were bluntly told "Get your jacket" and with that Marston threw workers out.
In 1889 and 1890 he is elected mayor of Wolverhampton. 
In 1894 there is a John Marston, Carriage builder of 24, Bradford Street,
