Cyr is a plantation in Aroostook County, settled in 1824. Originally Township L R2, it was organized for election purposes in 1857. Cyr had its formal organization confirmed on March 12, 1870. In the 1880’s it had a population in excess of 500 supporting four public schoolhouses. (The Governor Brann Historical Schoolhouse is now located in the Acadian Village historic site in Van Buren.) During the Civil War, this small community sent 25 men to aid the Union cause. Eleven died in that conflict. — Maine, An Encyclopedia
