Do you have their marriage certificate? I can only see one possible marriage but it does not tally with the 1881 Census. Their son Fred was born around 1874/75
1881 Census
RG11 / 4545 / 137 / 46
Belvedere Road, Batley
possible marriage
William Henry Brearley / Annie Jowett
March 1879 / Dewsbury
There is no birth on Freebmd for a Jowett around 1850. Will re-check for you.
