The exact location of the Mission of the Guardian Angel in unknown but various historians have proposed a number of sites in the Chicago area. John Gilmary Shea published an English translation of the letter in 1861; however, Chicago historian Milton Milo Quaife, writing in 1913, noted that Shea's translation "frequently departs from the original manuscript" and that differences in translation may account for some of the different sites proposed. Quaife, working from a duplicate of the original manuscript concluded that the mission was built on the banks of the main stem of the Chicago River, somewhere between
the forks and its mouth in what is now downtown Chicago. Other locations proposed include
Lake Calumet and a location near
Goose Island. Other locations suggested have been Evanston by the Evanston Historical Society, Lake Calumet by Hurlbut, Churchill Woods by V. P. Web, Winnetka by the Saints Faith Hope and Charity Parish Winnetka, the Merchandise Mart by Swenson, Highland Park by Bower and Dooley, the area around LUMA (a Loyola University campus) by Loyola University Chicago, Gross Point by Grover, and Wilmette. ==See also==
