In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Millbrook like this:
MILLBROOK, a fishing-village and a chapelry in Maker parish, Cornwall. The village stands on an inlet of the Tamar, 2 miles, across the Hamoaze, S of Devonport r. station; has a post office under Devonport, and fairs on 1 May and 29 Sept.; was once a market-town and a borough; and has a pop. of about 1,500. The chapelry has no definite limits; and its statistics are returned with the parish. The living is a p. curacy in the diocese of Exeter. Value, £160.* Patron, the Earl of
Mount-Edgecumbe. A battery, for the defence of Plymouth sound, has been erected on heights near the village.
