Monteith’s great-grandfather James Monteith was a small Perthshire laird in the Aberfoyle area, whose livelihood was under constant threat from the depredations and blackmailing of Highland reivers. After his death his son Henry moved south and set up as a market gardener at Anderston, then a village near Glasgow. He fought against the Jacobites at Falkirk and died ‘a staunch Presbyterian of the old school’. His eldest son James Monteith, who was born in 1734, took up handloom-weaving. He prospered, especially when he began to import fine French and Dutch yarns, and became a cambric manufacturer on a large scale, with a bleach field near his house and warehouse in Bishop Street. Three of his sons joined him in the cotton manufacturing business, which expanded dramatically with the introduction of power looms. John Monteith, the eldest, formed his own company in 1801 and established the first Scottish power loom factory at Pollokshaws. James Monteith, the second, was initially a dealer in cotton twist at Cambuslang and in 1792 bought David Dale’s Blantyre cotton mill. The start of the French wars the following year threatened disaster, but he averted it by adopting the fashionable London method of selling linen and cotton cloth by public auction, which made him £80,000 in five years.
Unlike his father and brothers, Monteith was a staunch church and king Tory.
Monteith gave general but not entirely slavish support to the ministry.
At the general election of 1826 he was defeated in Linlithgow Burghs, but he had already been returned unopposed for Saltash on the Russell interest.
Monteith retired to private life. He died at Carstairs House in December 1848, ‘in his 85th year’, and was succeeded by his only son Robert Joseph Ignatius Monteith (1812-84), a Roman Catholic.
