A William Gorst of the right age shows up in 1871, 1881 and 1891 with father John R Gorst, a coach trimmer, but John's wife is Mary, not Ellen. How sure are you of Ellen's name? Perhaps John was married twice?
I'll list the families anyway - if this is the right lot, the 1871 census gives you an extra generation!
