Hi Margrette,
I have looked at NSW Births, Death and marriages and here is Annie marriage details.
4313/1902 CROUCH ROBERT P WHYBURN to ANNIE WEST MAITLAND
here is Annie's birth details
13989/1875 WHYBURN ANNIE father:DAVID mother:LUCY MAITLAND
here is Annie's death
30713/1965 CROUCH ANNIE father:DAVID mother:LUCY NEWCASTLE
and as you can see she is my ggrandfather's sister.
The cemetery I mentioned is on Old Maitland Road at Bishops Bridge. It is a bit run down and is not an active burial site, very old graves are here.
Do you live in Sydney?
