Caroline - hi
Here it is - remember, this is
not the one who was Robert's father; Robert's father was Henry John Gibbs and wasn't born until later in 1861 - he does not appear on this census
1861
RG9 P. 1339 Fol. 4 Pg. 2Knighton Heath, Canford, Dorset
Thomas Habgood Head M 54 Ag Lab B. Dorset Hampreston
Mary Ann Habgood Wife M 45 B. Dorset, Poole
Mary Ann Gibbs Dau in Law Un 20 B. Poole
Thomas Wells, father in law Wid 61 Ag Lab B. London
John Gibbs Grand son 1 B. Dorset, Canford
I would guess that daughter-in-law here, as applied to Mary Ann Gibbs aged 20, probably means step daughter (the expressions were inter-changeable

)
Hope this helps
