The town of Irasburg was chartered on February 23, 1781 by the Vermont Legislature. It was one of three Vermont towns named for Ira Allen, the principal grantee (Ira in Rutland County and Alburgh in Grand Isle County being the others).
Irasburg was granted to Ira Allen, Roger Enos, Jerusha Enos (wife of Roger Enos), Jerusha Enos, Jr. (wife of Ira Allen), Roger Enos, Jr. and others by the Vermont General Assembly. Ira Allen later obtained the rights of the other proprietors, and he deeded the town to Jerusha Enos, Jr. as a wedding gift in 1789.
Irasburg was caught up in Ira's financial disaster and all of Jerusha's land was sold at sheriff's auction for back taxes. Ira's nephew and adopted son Heman bought the land and gave it back to Jerusha.
