Hay up Ell,
Well theres Gertrude born 1880, before they were married. They married 25th Dec 1880. Alfred 1883, Walter 1886, Jonas 1889, Emma 1891/2, mary 1895, John 1897, Elizabeth 1899, and Rohna ?. The dates could be a year out cos I've taklen them from 1901 census.
John the father is around 1861, and poor old Emma isn't really when or where she was born as its tends to be different on every census I've got for here.
I'de find a John Rodgers born to Mary Rodgers in Worksop, but theres no father. So I have no clue.
Thanks again Ell for your help.
