No, Wilsons' 1819 Key Pattern Book simply calls it Grant.

My intent was to lay the origin of the connection to the Grants with the old Wilson's books rather than any historical precedent. Should have left out the whole bit about the regiments in hindsight; it's irrelevant to the argument from the get-go. Thanks for catching that one...
The 42nd connection with the Grants is first noted in the Cockburn Collection (1810-15). Of the four specimens of 42nd tartan in the Collection, No 4 is named Grant of Grant.
