Mac Mhatha, son of Matthew, q.v. Alexander McMath of Dalpeder resigned 
      the office of coronator of Nythisdale in 1468 (The Register of the 
      Great Seal of Scotland, Volume II, Doc. 974).  Dalpedder in 
      Dumfriesshire is recorded in 1538 as the seat of the family (The 
      Manuscripts of the Duke of Buccleuch and Queensberry, 16), which ended 
      in an heiress, Bessy McMath, who married John Johnstone of Esbyshields.  
      Thomas McMath witnessed an instrument of Sasine in Dumfries, 1506 
      (History of Dumfries by Rogert Edgar, p. 228), and M'Math of that Ilk 
      appears in the list of freeholders of Dumfriesshire in 1597.  Edward 
      M'Mathe appears as merchant in Edinburgh, 1600 (Register of marriages 
      for the parish of Edinburgh, 1595-1750).  John M'Mayth was 
      retoured heir of Roger M'Mayth, his father, in lands in barony of Sanquar, 
      1601 (Retours, Dumfries, 12).  William Mckmath was "boxmaster 
      to ye Incorporation of the Walkers" in Edinburgh, 1684 (Book of the Old 
      Edinburgh Club, Vol. IX, p. 121).  "In the seventeenth century a 
      family of merchant burgesses of the name of Macmath flourished in 
      Edinburgh, and the arms assigned to them in Funeral Escutcheons . . . are 
      certainly founded on M'Naught" (Scottish Arms by Robert R. Stodart, 
      Vol. II, p. 187).
