Hello,
This reply is a good bit out of date but in relation to the records for the cemetery at Assumption hill, I have just finished a survey of the remaining headstones at the cemetery and there are just 250 names remaining from approx 900 burials.
While doing my research I could find no other records relating to the cemetery. It was closed many many years ago but was taken over a few years ago by the city council, by pure coincidence it was reopened today by our Lord Mayor as a park for the people of that area. If you would like any further information, please contact me.
Regards,
Sean
