My Agnes is the daughter of a John Anderson and an Unknown Campbell; presumably, the person who registered her death had forgotten the first name.... Although I was lead to believe that John was a maltman, ie working with whisky, there was not a distillary at Inverary: apparently they blended whisky brought to the Castle.
A brewer working with beer is a similar occupation, and possibly to an engineer (her husband & son) they might be the same thing. I think too that I have found some evidence that my Agnes' mother was Elizabeth: second daughter is called Elizabeth. I plan at some time in the future to contact Inverary Castle to ask if they have any records of John's employment: family lore does link the family with the Castle.
I have never seen it before, but information on the burial was written onto the death certificate. The funeral was undertaken by Wylie & Lochhead - a large and well-known Glasgow firm, and having checked their records, can confirm she was buried at Kilmalieu. It may be that your friend has a copy of IMs recorded fairly recently rather than the original burial records, and if this is the case, it may be that the headstone was damaged/broken/badly weathered by the time the IMs were recorded. Oh well
However, I think that this John and Elizabeth are probably the correct family, therefore would be grateful to receive any information about them that he/she may have. Also, if your contact in Furnace is able to provide a plan of the burial ground and info on the plots, it would make locating your relatives a lot easier.
Thanks for your help, and am looking forward to my trip to Inverary!
