I've found another family that seems to fit - in Norfolk although not in Loddon. I think the Javus should be Jabez!
1901 - Gt. Dunham, Norfolk
Jabez Warnes 36 Farmer b. Sedgeford, Norfolk
Charlotte Warnes 33 b. Russia, British Subject
Florence Warnes 9 b. East Dereham, Norfolk
Arthur Warnes 4 ditto
Gladwys Warnes 1 ditto
James 7 mths b. Gt. Dunham, Norfolk
plus servant
ref. RG13 - 1874 - 46 - 12
Whilst Javus could indeed be Jabez, wife Charlotte was born in Russia which ties in, surname is Warnes and the following census does show they'd had 12 children, 4 of whom had died and alot of their names tie in. However, I can find no trace of a birth for a Florence Mabel Gwyneth Warnes anywhere and births index would suggest their daughter Florence was actually Florence May. She is the right age for F M G. The registration district for the area they lived in was Mitford and this seems to be the births of their known children:
Florence May Warnes Jun.1891 Mitford
Arthur Edward Warnes Jun.1896 Mitford
Gladys Warnes Sept.1899 Mitford
James William Warnes Sept.1900 Mitford
Charley Warnes Sept.1902 Mitford
Thomas Albert Warnes Jun.1904 Mitford
Ena Louisa Warnes Jun.1906 Mitford
Lily Rosanna Warnes Jun.1907 Mitford
Robert J. Warnes Jun.1911 Mitford
James William b.1900, died 1902 - there are a number of infant Warnes deaths in the period so the other 3 that died are probably amongst them.
At the moment it looks like Florence May Warnes is the one who later is Florence Mabel Gwyneth.!!
There is no family on the census which matches all the names you give plus there is no Warnes/Mabel Flood marriage and no F M G birth.
However, the surname is Warnes, it is in Norfolk, Javus sounds like Jabez, a Florence of the right age, mother born in Russia and they had in total 12 children (with 2 others being Ena and Lily). Too much seems to fit here.
Until you come back and comment we can do no more.
