First recorded in the Vestiarium Scoticum which was supposedly based on an ancient manuscript now known to have been forged. The original illustration shows the three main strips in a very dark shade of blue. There is no evidence of a Hamilton tartan prior to the publication of the spectacular work. The authors, the Sobieski Stuart brothers, enjoyed a popular following amongst the Scottish gentry of the period and it is probable that the design can be attributed to Charles Edward Stuart (Allan Hay).
This tartan dates to 1842.
The US Coast Guard tartan is based on the Hamilton tartan in honor of Alexander Hamilton, first US Secretary of the Treasury and founder of the US Coast Guard.
