Mary Ann HIND, 46, Head, Widow, Laundress, born Westminster
Lavinia H Hind, 14, Daug, Unm, Laundress, born Westminster
W FOSTER, 18, Friend, Confectioner (out of employ), born Westminster

J Quelch, 28, Son, Unm, Occp?, born Weedon, Northants
Mary Quelch, 20, Daug, Unm, Machinist, born Weedon
J/Mary are down as Mary Hind nee Quelchs Children but should be her Brother/Sister and Harrietts Children I think.
Probably James born c 1842 and Mary c 1841 from 1851 census.
Names and POB seem to fit but was Mary born c 1825 a child of Harriets before she Married?
