(amost 21) year old Scot in South Texas

[Deasan]

The earliest recorded and most prominent family to bear this name assumed it from the five merk lands of Cochrane near Paisley in Renfrewshire: though it was said that some MacEacherns who had been removed to the Lowlands adopted the name, while its affinity to the Irish Corcoran is suggestive.

Wonderful family history and very interesting stuff -thanks for sharing Joshua.
Have you read The Highlands by Calum I. Maclean? He was the brother of the poet Sorley MacLean and a brilliant folklorist. This book records his adventures collecting folklore in the Highlands. Also, if you are interested in the history of Highland dress then H.F. McClintock's Old Irish and Highland Dress is a super read (though dear in price, many University libraries have a copy of it). Just a few books of many-these should keep you burning the midnight oil for a little while anyway.
