Interesting -
I found on the IGI the entry for Sarah Alicia Wilstrop, christening 18 January 1846 Rufforth, parents Robert and Sarah, so matching the daughter in the 1861 census and also a Mary Hannah 14 April 1850 Rufforth and Elizabeth 15 October, 1844 Rufforth
The list also showed up a group of christenings of children to a Robert Wilstrop and Elizabeth, obviously a previous generation, some on 6th October 1816 and some on 19th December, 1816, one on 22 March, 1818, so these may well be the same family having a couple of job lots of christenings done (names are all different) but couple be two different families, but what caught my eye was a David Hick Wilstrop, christened 19 December 1816 Rufforth, I would suspect that it's too much of a coincidence for these not to be connected to the David Hick Willstrop found in later censuses. One of those on 19th December 1816 was a Robert, so again probably the one in the Rufforth 1861 census.
Also a Robert Wilstrop married Elizabeth Hick July 1802 Rufforth
These are all "extracted" entries transcribed from the local Parish Registers, however, you would still be advised to see the originals for yourself.
