What nationality would you be if your great grandmother was born in Scotland but her parents were Irish?

AnswerWe cannot answer this question because you gave incomplete information; you did not say what nationality your father or his ancestors are, nor did you identify the nationalities of any of your mother's other ancestors. But based on what you did give, you would be at least 12.5% Scottish and 18% Irish. AnswerYou would likely be British, at least along that branch of your family. Because the Irish invaded Scotland and later the Scots invaded Ireland as part of the English conquest, there really are not sharp boundaries in this. It seems to matter most what culture each individual was brought up in, so where each person was born and raised often seems to decide whether they are considered to be Scots, Irish, Welsh, Cornish or English.

Answer

You would without doubt be a very British mongrel, and should be proud of it!
