Mornington Cemetery is a cemetery serving the Mornington Peninsula area of Melbourne. It is located at 40 Craigie Rd, Mount Martha.[1]
The cemetery was first Surveyed in 1855, and was originally called the Mt. Martha Cemetery, then the Moorooduc Cemetery.
It contains a number of pioneer graves for the district.[2]

The above is from Wikipedia which is very keen on contributors providing sources for claims. Was [2] proof of the claim that the cemetery was originally called the MOUNT MARTHA Cemetery, a claim that certainly needs to be verified? No! It provides a link to Valerie Wilson's terrific articles about the pioneers buried there, a worthy service to readers. However the fact that it contains pioneer graves does not need to be verified; almost all early cemeteries would.

The cemetery measuring 1945 x 1000 links (389 x 200 metres) had an area of 29 acres 1 rood and 32 perches and it was originally called (drum roll -----) CEMETERY.

I've done my level best to verify that it WAS called the MOUNT MARTHA CEMETERY but it looks as if it never bore that name.

If it was, anyone who can provide proof, not just repeat somebody's undocumented claim, will become one of my history heroes!
