I am trying to locate Edward's family on the 1921 UK Census.

Edward died on the Somme in 1917 leaving his wife Gertrude Ada Bradley (1890-1974) and four (4) children:
Edward William Kilby (1910-1990)
Annie Kilby (1911-?)
Ronald Ivor Kilby (1914-1966)
Iris May Kilby (1916-1986)

Gertrude Ada Kilby (nee Bradley) married William Simmons in the 4th quarter of 1921 at Pontypridd district.

Does anyone know where Gertrude and the children were at the time of the 1921 census?

Thanks
Ian Watkins
