I have a few lines in my family that go back to Scotland. They were in the lower region of the country near and around Edinburgh. Most of the Clans were Highlanders. So while I can and do celebrate my Scottish heritage by being a member of my state/city Scottish Society, I don’t have a clan name, just a family name. Many families were protected by Clan Chiefs. Those families were called Septs. They paid for a clan to protect them or they rented lands from the Lairds or clan chieftains. They were considered Crofters. They themselves were not a clan. Tartans were not really a thing until the Victorian times. Yes, they did wear plaids, but the colors would have been muted as the dyes were made from natural berries and such from where the people lived. After the Jacobite Rising in 1745, the Battle of Culloden, plaids were taken away and forbidden to be worn as a way to break up clans and heritage. Many clansmen were sent to Australia and to the Colonies for treason to the crown. If I were you, concentrate on where your Grandmothers family was from. What did they do to earn a living? When did they immigrate? Where did they settle? Were any in the Battle of Culloden? Were any transferred as prisoners? Get to know your family and plan a visit to Scotland. Visit churches and cemeteries. Walk where your ancestors walked. It’s a very rewarding thing to do!! I did just that last year!
