Hi Jane,
My 4xgreat grandfather William Quiney was born in Preston Capes, Northamptonshire in 1802. He was recorded as a druggist in the 1841 census, an ink maker in 1842, chemist in 1851 census, druggist in 1865, wholesale druggist in 1871 census, druggist 1881 censis, drug maker 1883. He died 7 Jan 1883 and was recorded as a wholesale druggist. In all this period he lived and worked in the Stepney, Tower Hamlets, Mile End area of London (Middlesex). I don't know when he moved from Preston Capes to London. Anything you can find would be wonderful.
