Salaams Jim, Lovely subject by Cathey! Perhaps this 45 is a reference to this Wikepedia historical page Quote''The Jacobite rising of 1745, often referred to as "The 'Forty-Five", was the attempt by Charles Edward Stuart to regain the British throne for the exiled House of Stuart, and recreate an absolute monarchy in the Kingdom of Great Britain[citation needed]. The rising occurred during the War of the Austrian Succession when most of the British Army was on the European continent. Charles Edward Stuart, commonly known as "Bonnie Prince Charlie" or "the Young Pretender," sailed to Scotland and raised the Jacobite standard at Glenfinnan in the Scottish Highlands, where he was supported by a gathering of Highland clansmen. The march south began with an initial victory at Prestonpans near Edinburgh. The Jacobite army, now in bold spirits, marched onwards to Carlisle, over the border in England. When it reached Derby, some British divisions were recalled from the Continent and the Jacobite army retreated north to Inverness where the last battle on Scottish soil took place on a nearby moor at Culloden. The Battle of Culloden ended with the final defeat of the Jacobite cause, and with Charles Edward Stuart fleeing with a price on his head. His wanderings in the northwest Highlands and Islands of Scotland in the summer months of 1746, before finally sailing to permanent exile in France, have become an era of Scottish history that is steeped in romance.''

This is my understanding as well. My great uncle Max was president of the clan Maclean here in America when I was young and this is what he explained to me which sincs up with all that I've read since. It better be it's incorporated into a tattoo of the clans history I have.
