Oldest MacDonald sett?

[figheadair]

I'm hoping to hear from our resident experts on this.
But what MacDonald tartan has the oldest known pedigree associated with the clan. And to what year can it be reliably dated
Thanks David

Clan Donald is fortunate in having a number, probably more than any other clan, of tartans that pre-date 1800.

Both these tartans are proven to date to 1746 and unlike tartans in portraits, the settings can be verified from surviving specimens.

MacDonald of Borrodale

MacDonald of Kingsburgh

The original MacDonald of Glenaladale plaid was taken to PEI in 1773 but is thought to have been worn at Culloden.

The MacDonald of Keppoch tartan is also taken from a specimen of an 18h century plaid, likely to be pre-1760. And then there is the c1750 portrait of the MacDonald Boys in which the younger wears what we now call the Lord of the Isles (Red).
