I found some information through an alternate spelling as D'Artigue. I think it is related to the lodge as a search found that both spellings are used in relation to this place.
According to pioneersalberta.org "D'Artigue was a professor at Queen's University at Kingston, Ontario before joining the NWMP at Fort Macleod in 1882. After leaving the force he ranched in the Ghost River area. He later wrote a book believed to have been called 'Forty Years in Canada'. D'Artigue was born in Southern France."
As per another source there was land set aside for a school that was never built because it turned out there was not enough demand. Children ended up going to other schools in the area.
