Letters relating to the Demerara-Liverpool shipping business of the company Inroy Parker/Sandbach Tinne.

Administrative / biographical background
James McInroy came to Demerara in 1782, and planted or acquired a sugar plantation soon after his arrival. By 1790 he was joined by Samuel Sandbach, Charles Stewart Parker and George Robertson and the company McInroy Sandbach and Co. was founded. At first the head office was in Glasgow under the name McInroy Parker & Co., and in 1804 a branch was formed in Liverpool which later became the company's headquarters. In 1813, Philip Tinne was taken into the partnership and the company became known as Sandbach Tinne and Co. in Liverpool and McInroy Sandbach and Co. in Demerara. They were importers and exporters, shipping and estate agents, mainly concerned with the trade in sugar, coffee, molasses and rum and were involved in slavery. The first accounts available at Companies House are for 1948. These show Parkers, a Sandbach and later a Tinne still involved in the company. However, they are part of a larger group Demerara Co. Ltd. In the early 1960's the company experienced its first losses and several shake ups in the directorial board followed. Business continued to go badly and by 1969 the company had been taken over by Jessel Securities. Sandbach Industries went into liquidation in 1969
