He was born in Old Monkland on 4 July 1824, the son of Isabella Robertson and Alexander Christie (1789-1859), a colliery-owner and ironfounder.
[1] On his father's death in 1859 he inherited vast lands in Ayrshire, Midlothian and Clackmannanshire, largely focussed upon coal-mining and iron-foundries.
This estate provided a more rural environment than his other landholdings and focussed on farming, forestry and raising deer and pheasant.
John Christie's eccentricity increased, dyeing his moustache and proposing to a woman 50 years his junior.
Alice Christie married Robert King Stewart, KBE, of Murdostoun at the age of seventeen in 1881.
