What about Scottish Gaelic? One of the small facts that I discovered in my research is that Barvas parish, on Lewis, has the highest concentration of native Scottish Gaelic speakers left in the world. I also discovered that Barvas is where both my great, great, great grandfather - Iain MacIver - and my great, great, great grandmother - Margaret Gunn - lived. (Her family migrated two years after he did, and they married in Canada.)
Scottish Gaelic (different than Irish Gaelic), has been considered a dying language, but a resurgence of interest in it - both within Scotland and elsewhere in the world - is slowly growing. If you are interested in learning a little of 'the Gaelic,' Beag air Bheag (which means little by little) is the best place to start!
Finally, here are some of the Scottish Gaelic words that you might find in my books:
Màthair (MAH her) – mother
Fáilte (FAL chê) – welcome
Maidainn mhath (MAH deen vah) – good morning
Tapadh leibh (TAH puh leev) – a respectful thank you
Seolta (SHOLE tuh) - ingenious or clever
Dun (DUN) - fort
Carragh (CAR ugh) - rock
Pronunciation for the Gaelic names used in my book(s) are on the Characters page.
