Physician. Boswell mentions meeting a Dr. Garie at Sir William Maxwell's on October 7, 1762. Pottle, in Journal of my Jaunt, 1762, identifies him with William Garioch.
Life with Boswell:
Boswell described him as "a physician, who has been tutor to the knights of this family [the Maxwells of Springkell] for two generations, a man upwards of seventy, nonjurant and High-Church, but is a quiet peaceable creature and never mentions principles. He lives in the house and seems to be very happy".
