Samuel Sandbach (1769 – 26 April 1851) was successively bailiff, coroner and Mayor of Liverpool, as well as High Sheriff of Denbighshire and a Justice of the Peace for Lancashire.
Around 1792, after working for some time as a clerk in firm that had been trading since around 1782 in one form or another, the partners were so impressed with the younger Samuel that they invited him to join their ranks.
[1] When trade and thus the income from it went into a downturn, two of the partners – George Robertson, an older, long-established merchant, and Charles Stuart Parker – decided to concentrate on development of existing plantations in Demerara.
[1][2] In 1813, the prosperous and well-connected Philip Frederick Tinne, a Dutchman of Huguenot descent, joined the Liverpool firm, which became known as the "Rothchilds of Demerara", as a full partner.
The enterprise grew to become owners of both ships and plantations and also exporters of coffee, molasses, rum and sugar from the West Indies to the British ports of Liverpool and Glasgow.
