These are my girlfriend's ancestors - Jack was a retired soldier/coal hewer who lived on 42 Regent St in Balby, Doncaster and Ellen was an Irish housewife. According to family stories, Jack left Ellen for another woman at least after 1921 and apparently their son chased him down the street and jumped on him in anger but that's a whole other story. 1921 census is where I last find them two - the 1939 register has all of their children all married and living on their own means. Any help trying to track them both down would be vastly appreciated

Jack was born in Ripley, Derbyshire in 1878
Ellen was born c. 1881-82 in Ballintemple, Co. Cork
