Help with the Jones family

[Helina]

According to the 1911 census this family had 5 children all living, can only find 4 so you maybe up to a challenge
Rosa Ann Jones born 1871 in Lydney, parents John Jones and Emma Coole.  On the 18th October Rosa married Thomas Jones in Parkend St Pauls.
The 4 children I have found via the GRO site and the census are:
Rosa  Jones born 1893 in Whitecroft, Gloucestershire, on family trees she has a second name Elizabeth, birth reg in Monmouth
Lilian Jones born 1896 Pillowall, Gloucestershire
Percy Jones born 1900 Lydney
Winifred Emmeline born 1907 Colefield

In 1911 the family are living in Penrhiwceiber Glamorganshire

Any help would be appreciated
