Irwin (Streamstown)

Various members of the Irwin family are recorded as the owners of land in county Sligo in the 1870s. McTernan notes that this branch had been prominent in Sligo social and political life in the eighteenth century, serving as magistrates, Grand Jurors and High Sheriffs. However, as the ninetenth century progressed the family tended to live out of the county, principally in Dublin. In 1883 Bateman noted B. Irwin as the owner of over 5,700 acres in counties Sligo and Donegal.
