As Thomas, the father, died between the 1851 & 1861 censuses this could be his burial, as all the children are baptised in the Old Church, Smethwick
Burial: 18 March 1852 Old Church, Smethwick, Staffs

Could this be Thomas, the father's baptism, again the same Church

Again, I can't see a marriage for Thomas & Sarah.
