I have alot of Irish in my background, and it's kind of complicated. This is all of my mother's side, my dad's side is all German, Russian, and Polish.
Before one of the early famines (probably around 1810 or so) part of the family came over and settled in Merrickville (they were the first settlers in that area), Richmond, and a few other places in Ontario. The people in Richmond owned an inn where the Duke of Richmond died from a septic fox bite.
My grandmother's family came from Ireland. And my Great Grandfather remembered his grandmother singing in Gaelic.
When we went to Ireland in 2001 we actually found the grave of one of my multiple great grandmother's. It's very hard to find a grave in Ireland because of the famine. But she died before everyone else.
This is only a little bit of family history, we literally have dozens of binders with trees and pictures and letters. I could go on but I won't. I love geneaolgy
