Yes Kate, on reflection I think the marriage date is more likely to be correct than the death date as the daughter didn't know parents or the correct time in Aust.. I keep choping and changing between marriage age and death age on the certs. I just wish I could find her Assizes record as I'm sure it gave her age. I have a feeling she was born 1804/5. I'll go looking in my files !! I think I found something at the Janet Reakes Centre at Hervey Bay years ago on the trial.
