Missing in 1861- (sorry another one)

[Margaret in Burton]

I have found Henry and Rhoda Stone on all census except 1861.

They married in 1860 in Kensington - Rhoda was Stone before she married as well.

1871 census has them in Kingston upon Thames, Surrey

The eldest two children were born in Kensington

RG10; Piece: 861; Folio: 53; Page: 4

This is them in 1871

Henry Stone aged 34 a Saddler (later he is described as a maker of leather goods)
born Paddington

Rhoda Stone aged 33 born in Frimley, Surrey
Alice Kate aged 9 born Kensington
Henry Thomas aged 7 born Kensington
Grace aged 2 born in Battersea

Where the heck are they in 1861
