I have copies of several letters as well as newspaper accounts of the Mackay brothers. Three of them Stephen, Samuel, and Francis all entered the British army together in 1756. I always thought it odd that all three with Scots surnames came from the Dutch Service into the British. Sameul and Francis were ensigns in the Dutch Guards; they were not serving with any of the regiments in the Scots Brigade. I lose track of them after May 8, 1764. On that date they exchanged their commissions with half-pay officers and went on half-pay themselves. I have gone through thousands of documents from the Loudoun Papers, Amherst Papers, and Gage Papers over the years. I was always fascinated by the Mackay brothers because they kept getting into trouble, or debt, or both. It seems their Colonel, Frederick Haldimand, was always trying to get them out of trouble and in the army because they were such good officers. Both men distinguished themselves at the Battle of Fort Ticonderoga and are mentioned in an account I have from a colonial newspaper. After Montreal capitulated in 1760, both Samuel and Francis tried to gain ownership of land around Ft. Chambly. I think that we are on the same trail and be able to complement each others' research.
