Austin Grimes, machinist, signed up for WW I giving his b.d. as 13 Nov 1876 in NYC. and Mrs. Orpha Grimes (sister) of Newburg, N. D as next of kin. He signed up 15 Dec 1915 in Calgary, Alberta.
I don't know if this is him or not but in Cadillac : prairie heritage pg. 300 it says:
Owen and Austin Grimes came from Langman, Saskatchewan. They purchased the S 1/2 15-6-0-13 and farmed for a few years before they sold their land to Remy Bourtin. They had a pool hall and a Dodge car agency in Ponteix. They returned to Lampman.

"Scotty" Morrison, George Scott, Austin Grimes - all good horsemen and dependable assistants in mixed farming.
