John Yeomans was killed on 3 July 1916 at Thiepval, Somme, France. I found his record on the Commonwealth War Graves Commission site: http://www.cwgc.org/http://www.cwgc.org/ It looks as though his age is in error 38 should be 35 but if you click on his name you will see that he is the son of Charles and Elizabeth. I don't think he was married.
The National Archives site has a medal card listed for John Yeomans - Private - North Staffordshire Reg. You can download the information on the card for about $7. (3 pounds 50 UK) http://www.nationalarchives.gov.uk/documentsonline/http://www.nationalarchives.gov.uk/documentsonline/ click on WW1 medals on the side of the page.
Judith Yeomans appears on the 1911 Canadian census as a waitress living in Saskatoon. She says she emigrated in 1911, age 21. So I don't think she ran away! You can find the Canadian censues at: http://automatedgenealogy.com/http://automatedgenealogy.com/
