His wife Sarah Moffett was the great-granddaughter of a "Kilty Officer" of a Highland Regiment who was awarded land in Ireland from William and Mary of Orange. So he faught on the "wrong side" you might say.
I would double-check this if I were you, as the first Highland Regiment wasn't raised until 1723, long after the end of the reign of William & Mary, and Highlanders generally favoured their opposition, James II.
