An early Proscription era tartan?

[figheadair]

Beautiful tartan, and fits well with the bright reds shown in some of the period paintings. Did the owner provide an opinion on where they think it came from (geography, clan, city, etc) or would you rather wait for confirmation and unveiling with the full paper?

I known where the name, date and place of birth of the original owner; plus when 9(1748) and to whom they were married but not yet where or where they lived thereafter. Hopefully that will all become a little clearer as I work through the paper.
