Donald Campbell (Macarthur) (b. 1826?), was the son of Malcolm Macarthur and Ann Macleod. He lived at 2 Enaclete for some time and was married twice, to Isabella Macleod in 1840 (though that suggests his birth date was earlier than 1826) and later to Catherine Macleod. The family emigrated to Quebec, Canada around 1851 (after the census).

The family appears to have been known as both Macarthur and Campbell.
