I haven't got a lot of info on Sarah Pickup, born c.1819, but according to her marriage certificate (when she married George Pickup, born c.1815, in October 1844) her father was a James Pickup whose occupation was labourer. Her age at marriage is just given as 'of full age', which is not very useful. Her place of residence is given as Higher Booths.
Looking back on the 1841 Census for England and Wales, I believe that I have found her living with (I presume, as no relationship is stated) her mother, Ann Pickup, and other family members at Goodshawfold, Higher Booths, in the parish of Whalley, Lancs. If you wish to look it up yourself, the P.R.O. (Public Record Office) reference is:- HO 107 / 506 / 11, folio 15, page 22. Also in the household on census night is an Annis Pickup, aged 4 years, who is (I believe) Sarah's daughter. I have a copy death certificate for Annis that shows that she died at Goodshaw Fold, Higher Booths on the 24th October 1852 aged 15 years and 11 months. She is shown as being the daughter of Sarah Pickup now the wife of George Pickup, power loom jobber.
Having said all that, I have seen your other recent postings that suggest that Sarah was the daughter of a John Pickup in the Eccles area of Lancashre, which probably means that we are looking at two different Sarah Pickup's. Never mind, hopefully the information will be of use to someone.
