Another misplaced military marker

A bright white marble stone marks the grave of John Robison (d. 1849) in Armstrong Cemetery.

But what is this? A Civil War marker next to it? Not if John Robison died in 1849!

Perhaps somewhere in Ohio there is another John Robison who should have this GAR marker.

In Memory of
JOHN ROBISON
a native of Scotland
Perth-shire Killin;
who died Dec^r 28^th 1849
Aged 56 years.
A UK website promoting tourism describes Killin today:

Killin is a delightful highland village at the west end of Loch Tay in west Perthshire. It is situated beside the river Dochart close to its junction with the River Lochay and just a few hundred yards from the point at which it enters loch Tay and loses its identity to the Tay, Scotlands longest river.

Killin is the largest and oldest of the many settlements in Breadalbane—‘Braghaid Albainn’—the High Country of Scotland. The name of the village comes from its association with the legendary Celtic Hero Fingal who, it is thought was buried here—‘Cill Fhinn’ meaning the burial place of Fingal.
