Thank you, Peter. This makes sense. The lad photographed is the great grandfather (1874-1947) of an enquirer after his subsequent years in the US. He was born in the parish of Dalarossie and Moy and emigrated to the US (Pittsburgh?) in about 1902. He was reportedly involved in the MacPherson Lodge of the Order of Scottish Clans in that city. In those days the Lodge may have adopted the Macpherson/Caledonia tartan.

Do any of you have any knowledge of the 'Order of Scottish Clans'?
