Hi Cando,
I've been getting help via PM with a very good friend, who shall remain nameless for a while.
No, I didn't notice a gap
The district is Wagga Wagga and it's 1877. William Henry JONES, to be precise.
I also have a couple of deaths missing from Wagga, but luckily have buriel records for proof. Plus another birth in Wagga, but have army records for him.
William is my Grandfather, so my direct line, the others are great-uncles and cousins, so I'm not as concerned to have their certificates.
Sorry norag, to have taken over your thread,

but the knowledge might be helpful to others as well.
Leonie.
