Mark, Grant was a past California State Amateur Champion (1918) and was one of the best amateurs of his day. His father was one of the founders of Burlingame CC in 1893. Grant attended Yale, but was unable to complete his scholling due to a degenarative deafness. He won the No Cal Championship in 1907 and the Pacific Coast Amateur in 1909. He met his wife, Elsie, during his travels in the UK and played in various tournaments including reaching the semi's in the '21 Irish Open and well as competing in the British Amateur and the Open. When he returned to the California with Elsie he won the No Cal Amateur twice ('16 & '17 and the So Cal Amateur in '17. He died in a fire while alone in his home in Carmel on March 17, 1966. In my research I've never seen him associated with any other design, but that doesn't mean he didn't give advice during all his travels. Hope this helps.
