True, but then what? I always see it noted that Capt Lewis Grant of Auchterblair who married Eliz Grant dau of John Grant of Carron is descended from James Grant of Auchernach through his third son, James Grant of Auchterblair, who married in 1629 Agnes, dau of Robert Grant of Lurg. In between is Robert Grant of Auchterblair c 1658-1670. But I've never seen anything that provides a definitive link between James, Robert and/or Lewis. Do you have one? If so, do share!
