Yes you are correct.
Mary Calder's baptism is in Hew Morison on 31st March 1765, and her marriage on 5th February 1793.
The latter record reveals that Hugh Doun was deceased, and that his wife was Marion MacKenzie.
There's a daughter Christian recorded as baptised in Durine on 8th December 1795. She died in 1858 aged 62 and is buried in Balnakeil alongside her husband George Sutherland (1785-1835), their son George (1835-1892) and his wife Ann Campbell (1836-1903). George senior died on 19th April and his son was baptised on 21st April. There isn't a good match for a birth under his name in 1785 in Hew Morison. I have a picture of the gravestone.
William Sutherland may be the man from Durine who married Christian MacKay and fathered eight children between 1829 and 1843. His patronymic MacEonic doesn't fit (should be MacNish but the location is correct and it may just be a sloppy transcription).
