ACV-44 (later CVE-44) was named Keweenaw Bay for a bay of Lake Superior along the northern shore of the upper peninsula of Michigan (NS0304408, map courtesy of Google Maps).

Assigned to the United Kingdom, 10 June 1943, and transferred under Lend-Lease on 22 October of the same year, she was renamed Patroller. A "Patroller" is an individual who walks or goes around or through an area, building, etc., to make sure that it is safe. The coat of arms was suggested by the ship's officers and possibly depicts a Chippewa Indian brave, since the Chippewas (also known as Ojibwe, Ojibwa, or Saulteaux) live in the L'Anse Indian Reservation in Keweenaw Bay, the original name of the ship (blazon courtesy of Tommy Trampp).
