Hi Kris
This appears to be the family in 1851 Census and the marriage and birth of Rory.
1851 Census Houghharry Nth Uist Inverness Scotland
Donald Mcdonald 36 Inverness farmer
Kersty Mcdonald 34 1817 inverness
Rory Mcdonald 4
Alexander Mcdonald 2
Ann Mcpherson 60 1791 mother in law inverness
I believe this to be the marriage but Christy's mothers name from the 1851 census is confusing unless she married again. Iam just checking that out.
