Usher's father, whose name he shared, Andrew Usher (1782 – 1855), was a prominent Scottish brewer who had experimented with the blending of whisky in the 1840s.
He had two sons, Andrew II and John.
Andrew Usher II was made a partner of Andrew Usher & Co of Edinburgh in the late 1840s.
 Andrew Usher II perfected the eventual blending of whisky and as such is sometimes called the 'father of Scottish whisky'.
The subsequent blending and mass distillation enabled whisky to grow from a drink rarely consumed outside the United Kingdom, to be one of mass export.

Andrew Usher II was one of the three founders of the North British Distillery; the other two were John Crabbie of Crabbie's Green Ginger and William Sanderson, whisky blender of Vat 69, who both served as directors of the NB distillery.
 Andrew Usher II was the first Chairman of the NB Distillery, serving from its start in 1885 until shortly before his death on 1 November 1898.
 Andrew Usher II and his brother John Usher, as partners in Andrew Usher & Co, were also the proprietors of the Edinburgh Distillery.
