Hi Babs
We Rootschatters would love to help you further, so can I quickly get back to basics and go over what you have so far on the Gaz(z)ard front.
Elizabeth, the daughter of William Gaz(z)ard was born in Woolwich in 1884 and married Albert E Weller in Brighton in 1908. She would therefore have been 24 when she married. 3 questions
[1] What was her occupation when she married?
[2] Was there any indication that William Gaz(z)ard was alive or dead at the time of the marriage?
[3] Were there any other Gaz(z)ards as witnesses on that marriage cert?
You have also told us that she was probably one of 13 children, but have given us no indication of any of the names (especially the more unusual ones) or the ages of her siblings, nor any idea whether she was amongst the eldest or youngest. Nor do we know when she came to Brighton or what brought her there.
Observations
She would not have been on the 1881 census, but her father should have been (either married or unmarried) If married, it is possible that there were elder siblings on that census too. Think you need to apply for a copy of her birth cert from 1884 if nothing else, to see her father's occupation then, the family address and her mother's maiden name.
That info should then help you find the parents with Elizabeth on the 1891 census and from there you can track back to 1881 and forward to 1901.
There appear to be no William Gaz(z)ards as brushmakers on the 1901, so I suspect the father had another profession earlier.
