Hancock Family of Somersetshire

I have found details of my maternal great grandmother Jane Hancock born 1844 in Somerset, England, and details of her birth and marriage, and birth records of her 9 siblings, but I am having problems finding marriages for those siblings. When I find a marriage record of any of them which appears to be them, I cant then find them on the census with their spouse, and would appreciate assistance of anybody else who is researching this same Hancock family, all of whom were born in the same county and whose birth was registered at the Axbridge registry office.
