Alas, a quick report from my rellies …. NOT yet found the twin girls but they have checked and there’s probably another baby’s baptism missing too ….
City of Sydney has recently updated their Old Sydney Burial Ground excel spreadsheet …
So, Just popping some information, likely Lady Di already has this, but sharing here

https://www.cityofsydney.nsw.gov.au/history-archive-collections/archivesDoes not seem to have been inquests for those three deaths.
https://www.records.nsw.gov.au/archives/collections-and-research/guides-and-indexes/coroners-inquests-index I add … A particular CD is no longer working for me, so I cannot do some of the searches I used to do, sorry, I guess I will have to make do with online efforts.
Ann SUMMERVILLE burial, Vol 2A, line 1665, 1802 and Vol 4, line 1122, 1802
William G SOMMERVILLE burial Vol.2A. line 1148, 1795 & Vol 4, line 700, 1795
