When did the grahams first arrive in Ireland?

The Grahams first arrived in Ireland during the 17th century, particularly around the time of the Cromwellian conquest in the mid-1650s. They were part of the influx of Scottish settlers, primarily from the Scottish Highlands, during this period. Many Grahams settled in counties such as Down and Antrim, contributing to the cultural and demographic changes in Ireland at that time.
