It might be possible to see:
1841: Elie STOKES, b. 1817, age 24 RR (possibly Sarah's brother, which would enable me to see the family)
As mentioned below: Sarah ROSE (STOKES) b. 1822 is married by the time of this 1841 census.
(ROSE/STOKES m. 1841 - I have to get this marriage certificate too, along with PARKES/SMITH m.1874.)

Mary PARKES b. 1853, Phillis, Isaac ...births were registered as SMITH because the Joseph PARKES/Hannah SMITH marriage took place after all the children were all born - m.1874
