A David Christison married Isobel Christie in 1799, Lochlee, Angus. Their family all born at Lochlee:

Charles Christison (1812) married Isobel Paterson at Lochlee, Angus in 1838. Banns 1837 Lumphanan, Aberdeen. They went on to have:

It looks in the 1841 Census as if Isobel Paterson was entered under her maiden name.
