Lachlan's old man
Despite the connections he might have had, and which his wife definitely had, it's said Lachlan's father was either a fisherman/crofter, a miller, or a carpenter. Not exactly even lowly nobility. And frankly, if he was a crofter, there's not much lower he could go.
The photo below is of the remains of a mill at Ormaig. If Macquarie's father was a miller, and if they lived at Ormaig (see the orange circle on Map U04 down below) this could have been his mill.
