The County of Clackmannan had one detached part, which consisted of portions of the parish of Logie and the parish of Stirling, situated at Causewayhead and the eastern half of the Abbey Craig, and had its longest common boundary with the County of Stirling. Cambuskenneth resided within the parish of Stirling, but the County of Clackmannan.
There were three parishes situated partly in Clackmannan and partly in other counties. These were:
Alloa, Logie, and Stirling.
Around 1891, the following were the changes made to the county boundaries.
With the County of Perth.
Alloa.
The parish of Alloa was situated partly in the County of Clackmannan and partly in the County of Perth. The Perthshire portion of the parish of Alloa was transferred to the county of Stirling and to the parish of Logie. It consisted of about four acres of land situated at Gogar Haugh.
With the County of Stirling.
Alva.
The parish of Alva formed a detached part of the County of Stirling. In 1891, the parish was transferred to the County of Clackmannan.
The following areas were transferred from the County of Stirling to the County of Clackmannan (while remaining in the parish of Alva):-
The police burgh of Alva, with all the subjects therein contained, these subjects constitute by far the greater number of the subjects transferred. The following landward subjects are thus transferred:

Logie.
The parish of Logie was situated partly in the County of Clackmannan, partly in the County of Perth, and partly in the County of Stirling. The Clackmannanshire part of the parish was in three portions. One was in the detached part of the County of Clackmannan situated at Causewayhead. It has been transferred to the County of Stirling, while remaining in the parish of Logie. The second consisted of the existing district, adjoining the parish of Alva; it is retained in Clackmannanshire. The third consisted of the Blackgrange property; it is retained in Clackmannanshire but has been transferred from the parish of Logie to the parish of Alloa. In the case of the last-named portion there is a slight rectification in the county boundary, whereby, instead of running along the centre of the Alloa and Stirling road as previously, it is made to run first along the one side to Gogar Loan and then along the other, thus dividing the road transversely instead of longitudinally between the two counties.
Stirling.
The parish of Stirling was situated partly in the County of Clackmannan and partly in the County of Stirling. The Clackmannanshire part was situated at Cambuskenneth, in the detached part of the county. The parish of Stirling has been placed wholly in the county of Stirling.
