Hi Jean, if your still watching this message thanks for the information on the death of Margaret on the 30 August 1875.
With regards to a what may be inscribed on her grave, I looked up the Rushen parish and can see that out of the 4 churches that make up the Parish, Kirk Christ Church built 1775 has a grave yard. St Catherine's & St Peters do not have grave yards and St Mary's was built in 1884 which is after she died.
I'm hoping to find her grave at Kirk Christ Church, however as she was married it may read Margaret Reid.
Can anyone offer information on where I could look for this. Many thanks Sharon
