Their most recent readjustment was made by the Boundary Commissioners in 1891. Previously the county contained four parishes Alloa, Clackmannan, Dollar and Tillicoultry, and portions of the parishes of Logie and Stirling. The Clackmannan portion of Stirling parish was transferred to Stirlingshire. The Clackmannan portion of Logie parish was divided into three parts. One was transferred to the Stirlingshire parish of Logic; a second was united with the parish of Alva, which was wholly given to Clackmannanshire; while the third part was absorbed by the parish of Alloa.
