NAS CS 271/39548 is a Bond of Caution drawn up by Daniel Angus merchant of Greenock concerning surety for William Robertson ship master of Greenock in a dispute with William Wood on 10 March 1791. William Wood, along with John Ballantyne, were trustees for James Hunter & Co of Ayr Sugar House, and Robertson, as a partner in Alexander Adam & Co merchants of Greenock, owed the sum of £21.3s.3¼d for sugars supplied to him almost 12 years earlier.

I can find nothing more about this sugarhouse, however having just researched the St Christopher Sugar House in Edinburgh that turned out to be a warehouse, or shop, selling the produce of the South Sugar House in Glasgow, I am now wondering if this may have been a similar concern in Ayr. A James Hunter is listed(1) as a partner in the No.2 refinery in Sugarhouse Lane in Greenock in 1788 and I suppose there's a possibility that he could have used the Edinburgh warehouse idea to supply sugar directly to the good folks of Ayr.

More work needed !
