[3] It is estimated that, aside from his periods crossing the Atlantic, Marsden was never out of work again, gaining new employment always on the same day he lost it, including several apprenticeships in engineering and a position teaching at the Sweet Street Wesleyan Methodist Sunday School, which he had once attended.

[8] The family then moved to Newhaven, Connecticut in 1850, where Marsden's inventions and improvements continued to be conceived and produced, and it was here that he began to truly make a name for himself as a great engineer on the highway to fortune.

[10] In spite of the fire, Marsden was able to return a wealthy man to Leeds in 1862, setting up a factory for patent stone-crushing machinery to take advantage of the demand at that time for road building.

[11] He received 45 first class gold and silver medals and honours for his inventions, which continued to provide him with the wealth to enable him to donate both time and money to public life.

[13] It was said that "from the beginning he conducted the business of the town and of the Council without consideration of sect, party or denomination, acting with strict impartiality and goodwill to all", with "prejudice, passion, and personal preference has been concealed by a manly English patriotism”.
