I have not identified any Irish born ancestors in my direct line, which for me growing up in the West of Scotland is very unusual.
My daughter on the other hand has several on her Dad's side.
Catherine Guinan who married Ernest Kleeman at St Mary's RC, London in 1871 father John born Cork. I believe her to be the Catherine guinan born Youghal, Cork to John Guinan and Honorah loughlan.
William McCombe b somewhere in Ireland c 1827 death cert gives parents names as William McCombe and MAry Larmer. Lived in Ayr and Later Stevenston in North Ayrshire.
Isabella Kirk wife of William above b somewhere in Ireland c 1823, Death cert father Joseph, mother unknown.
Joseph Hill b c 1820 somewhere in Ireland, lived in Stevenston N Ayrshire
Elizabeth Howie, wife of Joseph above b somewhere in Ireland c 1814
Thomas McCulloch b c 1823 in County Down, lived in East Ayrshire
Catherine Mcginnes (and all variations of spelling) b c 1832 Ireland, gives place of baptism as Inishowen
John McCorgray who married Catherine McGinnes above in burnbank nr Hamilton in 1855. His parents daniel and Helen (nee Sweeney) came over too. I cannot find a record in Ireland. He gave his place of baptism as Donaghmore, Donegal. I will check the other Donaghmores incase the priest justmade assumptions. I have yet to find a McCorgray/McCorgrey/McCorgary/McCorgery who is not directly descended from Daniel McCorgray and Helen Sweeny.
Oh er, looks a lot more when you list them.
