The 1841 England census has
1841 DISTRICT 1. EPSOM, SURREY, ENGLAND CHURCHILL Harriett, age 60, saddler, not born in this County
Harriet, age 20, born Surrey
Matilda, age 20, born Surrey
John, age 9, born Surrey
I did not find Harriett in 1851 so could have died by then I suppose. Since John was not with her in 1841 I expect he died before then. Matilda is working as a servant in 1851.
Henry is in Epsom in 1851 - he is a widowerwith sons Henry, Albert and Charles. - let me know if you do not have his info. I can trace him for you. In 1841 he is with wife Margaret and sons Henry, Albert and one not yet named.
Harriet Susannah died 1843 - at least that is when her death was registered
