Trying to discover something about the background of this lady. She was born at Abdie to Alexander McLeod and Anne nee Smith, who had married at Abdie on 16 September 1797. I haven't established the exact date of her birth but using census results, would put it at abt 1806. It's likely that a Hugh McLeod born at Abdie on 15 December 1799 to Alexander McLeod and Anne nee Smith was an older brother.
Agnes McLeod married at Abdie on 17 October 1831 to Walter White (1803-1884), born at Freuchie, Falkland, Fife, a son of Robert White and Margaret nee Waddell. They had 5 children - two of their sons and three (possibly four) grandchildren emigrated to New Zealand.
There is a family story that says Agnes' parents did not approve of her marriage to Walter, who was a master shoemaker. The couple may have eloped, because the story also says that when her parents discovered Agnes had married Walter anyway, they promptly disinherited her. This indicates that
Alexander & Anne McLeod must have been people of some standing, but I haven't been able to find anything about them. Presumably they didn't regard Walter as having sufficient status to marry their daughter!
