In 1851 the family consisted of Richard 50 a labourer(in 1841 he is a grocer),Hannah 38, Eliza 9 Jane 4 and Mary 1(my ggrandmother)Hewas previously married i believe to a Margaret Turner whoi had connections with a Grocers and I found her death pre 1840 when his 2nd marriage tooknplace.
All in Westminster area though his 1st d Eliza was born in Lambeth.
