Someone said :
My family are from Northern Ireland, my sisters and I were born in Belfast and we moved down to Dublin when I was 18 months old. Belfast in 1976 was not a good place to be, as you can imagine...
Anyhow, I did a family tree project in 2nd year in secondary school and my mum and maternal grandmother gave a lot of help on that. I was able to trace my father’s family back to the early 19th century, farmers and town tradesmen in east County Derry, around Coleraine. My surname, Shiels, has Scottish origins and my paternal great grandfather’s family on my grandmother’s side, Gillespie, came directly from Scotland in the 17th or early 18th century.
My mother’s family, the McGeowns, were from Tyrone and were farmers. My mum herself grew up on a farm but the family moved to Belfast when my mum was 17 in 1959/60. My great great grandfather was a miller in Tyrone and his water mill was reconstructed at the Ulster Folk Museum at Cultra outside Belfast. My maternal grandmother, Elizabeth Gallagher, and here ancestors were from Ballaghaderreen in Roscommon.
I like what you said but ... the 'Scottish' are made up of three very different groups.
The original Picts
The later invasion of the monks and educators from the north of Ireland. These Gaelic people were called Scotti - hence the modern name of Scotiland or Scotland.
Then came the Anglo-Saxons who couldn't read or write so, naturally, the Scots were hated by them.
My family clan came from Scotland to Ulster in the 15th Century- after having gone there many hundreds of years before.
Your family name Gillespie means Mac Giolla Espeagh which means 'the son of the servant (or follower) of the Bishop'
It is from Ulster and the Western Isles of Scotland.
Lime my own name it probably went there and returned many generations later,
