James Montgomrey (1 September 1811 – 4 June 1883) ran a large timber mill in Brentford, Middlesex, that was in the family for 120 years.
In James' tenure it was considered to be the largest timber yard in Middlesex and supplied products to surrounding counties.
[5] In 1855, James sold part of his land to enable construction of Brentford Dock, designed by Isambard Kingdom Brunel to link the Great Western Railway with the Thames.
[5] The Montgomrey family were active Whigs cum Radicals and James and his father were founding members of the Reform Club.
In 1868 James was principal subscriber and chairman of the building committee for St Paul's Church and its school, and the same year he spearheaded the creation of the volunteer fire brigade, in which his sons again played leadership roles.
