If you still are able to do this, I would appreciate a lookup on the 1861 census, which I think is the only one they have at 1837online:
James and/or Sarah BRAKE, husband and wife. They could be living in Nailsea (Somerset) area, Bristol, or London. They would both have likely been in their 50s or older, and certainly no younger than 45. He is listed elsewhere as being a "watchman" at that time. Children living at home might include Sarah (b.approx 1831), Emma (b.1827 or earlier), and Mary Ann (b.1822 or earlier).
The children could also be living on their own or married (except for Sarah, who is unmarried at this time)- I know little about them at this time.
Thanks in advance!
