Hello Leanne,
I tyake it that the family in the 1841 is the one headed by John Davarell and his wife, Sophia.
There are baptisms for some of the children on Freereg and these are as follows:
Zion Independent Chapel.Born 10 March 1829, baptised 24 May 1829, James, son of John and Sophia DEVERIL.
Frome, St John the Baptist.24 February 1821, baptised Louisa, daughter of John and Sophia DEVERILL, abode: Butts. Occupation Weaver.
19 May 1823, Baptised Benjamin, son of John and Sophia DEVERILL. Abode: Butts. Occupation, weaver.
23 May 1825, baptised John, son of John and Sophia DEVERELL. Abode: Frome. Occupation weaver.
See below, there is one more which has gone out of order for some reason.
