the Frederick from the 1871 census could be a child of one of William's siblings.
James Henry Kent married Elizabeth Harris 21 Sep 1851 - don't think he's theirs
Jane Ann Kent married Samuel John Brown 3 June 1866 - they're in London from 1881 onwards, don't think he's theirs
Frederick Augustus Kent married Susanna Punnett 21 Oct 1861, she was born Folkestone about 1843, I think, but can't see them after marriage.
Possible marriage for Elizabeth Kent to George Lamble june qtr 1868, they don't have a Frederick with them later.
Elinor is in Moon Street in 1871 RG10/2114 folio112 pg 27 with a daughter Maude birth registered dec qtr 1869 and death dec qtr 1879. Elinor married Samuel Goss dec qtr 1876, no Frederick with them later.
Still to find George born 1829 and Henry John born 1837
