R.I.P.
Some of the 'eights' on the image of the copper plaque look like 'nines'. I have carefully compared the transcription with the plaque itself. -
Archibald John and Delia Anne are the parents of Lorna Delia Anne., Lorna Delia Anne is the daughter of the others.
The image of the copper plate is difficult to read. I transcribed the dates from the plate itself.
