okay, as I have a nosey streak and a shed load of credits for SP, I looked at the entry.
It reads as follows:
Dec 9th 1821 Macallum & Sinclair
Proclaimed with a view to their marriage with each other Andrew Macullum of this Parish (son of John McCallum of the Parish of of Buchanan) and Mary Sinclair, daughter of Arch. Sinclair feuar in Dunoon and the said parties were accordingly Married on the 10th day of December 1821 years
Which clears up my hesitation about this regarding the Mary Sinclair being a feuar, as it was her father, not her.
