[1] It was created on 24 August 1892 for Sir Archibald Campbell, 1st Baronet, the former Member of Parliament for Renfrew, with remainder failing heirs male of his own to five of his younger brothers and the heirs male of their bodies (one brother, Robert Douglas-Campbell, was excluded from inheriting the title).
Sir Archibald had already gained that style by being created a baronet (formally of Blythswood in the County of Renfrew, in the Baronetage of the United Kingdom) on 4 May 1880.
However John himself was also landed as the son of Colin Campbell, 1st feudal Scots Baron of Blythswood and that estate passed to another branch of the family.
The title became extinct on the early death of his son, the seventh Baron, in 1940 due to a car accident.
The principal country mansionhouse was Blythswood House, near Inchinnan, built in 1821 to the palatial designs of James Gillespie Graham, replacing the older small mansion of Ranfield, or Renfield.
