Last name of my great gandmother Angelina ???

[Rhododendron]

Looks like Fermintong to me.

As has been said before, there are a a significant number of Italian names in the region.

IMHO, I would have thought that if it were Greek, they would likely be Greek Orthodox rather than RC. Therefore I think the father's first name might be Marino - the Italian masculine of Marina.

This leads me to think that the mother's name might be a misspelling, and while I might be completely wrong - the end of the name might say 'tory' or 'tony' rather than 'tong', as the ink may have run a bit.

Therefore the end of the name possibly should read as '....toni'? Which is definitely Italian sounding.

Hope this helps

Here is the marriage registration :

John Butterfield and Anne Peripato

GRO Ionian Islands Civil Registration Marriages 1818-1864

vol 9
page 18
line 27

In my humble opinion, the first letter is "J" as in January (to the left) 3rd letter looks like an "r"
but I could be wrong.

The J in January looks diffrent from the the first letter of the surname*. I now think it says Fermintong.

* a very distinct loop 'below the line' in the J in January

That's what i see.

So whoever registered the death didn't realise they married in Corfu (presumably) rather than England.

The informant was the son Arthur. I have seen quite a number of incorrect mother's names on Australian d/cs. This may be Arthur's best guess at his grandmother's maiden name and a guess at the spelling by whoever filled out the form.

That's what I see also, but perhaps the registrar cut the loop short as it was infringing the left hand column.
It's only an opinion.

It's the stroke through the F that I think you're seeing, Malky

Being RC suggests a non-Greek origin for at least some members of the family. Wikipedia has a page on Corfiot Italians:

https://en.wikipedia.org/wiki/Corfiot_Italians

Near the bottom there's a reference to "Maltese Italians" in Corfu, brought in by the British in the early 19th century. These people of Maltese origin were also RC.
