There are two strong possibilities for John's birth:
TOOZE, JOHN ESCOTT

TOOZE, JOHN WESTON
GRO Reference: 1855 S Quarter in WELLINGTON - SOMERSET AND DEVON Volume 05C Page 357
William Tristram Tooze married Ann Escott in 1853 but died in Q1 1858
Here is the family in 1861 with Ann's father present as "Ascott"

The other one is the child of John Tooze b. c. 1810 and Mary Ann b. c. 1827

Note that William Westcott Tooze is in the household. John Tooze married Mary Ann Westcott in Q2 1855
Marriages Jun 1855
TOOZE John Wellington 5c 597
WESTCOTT Mary Ann Wellington 5c 597
So either Weston is just a mistake for Westcott or Mary Ann was a widow with a maiden name of Weston. This is quite likely given the age difference but I can't find any evidence.
