I'm a McQuarrie on my mothers side. seems from what i can find we helped break clan MacDonalds hold on northern Scotland (No more super sizing). Then we apparently made the mistake of joining a fight against Cromwell. I couldn't really find much evidence but we seemd to be from the isle of man or glass or thereabouts. Then we disappeared and there was a battle mentioned that Cromwell won. I then found Port Macquarrie and MacQuarrie harbor in Australia and Tasmania, founded about 1 year or so after that battle. Seems we may have got the boot.
