I realise that it has Edith not Evelyn but it looks like only the initials were written originally with names added later (I've put the later additions in purple so you can see what I mean). I checked the 1911 census and the following family are together.

Eliza SMITH 75
John T FAVER 35
Ellen 36
William Henry 14

The marriage cert would confirm the father and hopefully ages,
