John A. Humphrey
John Albert Humphrey was a mill owner and political figure in New Brunswick, Canada. He represented Westmorland County in the Legislative Assembly of New Brunswick from 1872 to 1878 and from 1883 to 1890 as a Liberal-Conservative.
He was born in Southampton, Nova Scotia and was educated at Amherst, Nova Scotia and Mount Allison Academy. In 1855, he married Sarah Harris. Humphrey owned sawmills and woollen mills and was also director for several companies in Moncton. He was defeated in the 1878 general election. A small settlement known as Humphreys Mills, now a neighbourhood of Moncton, grew up around his mills on Humphreys Brook, a tributary of the Petitcodiac River. As of 1996, the John A. Humphrey Residence located on Mill Road is now a historic property. He died in 1895.
