The Blackburns I am interested in lived as missionaries, hoping to bring the local Irish to their faith. Little headway was made and the families made their way to Pennsylvania to the much more successful New Garden of Chester meeting houses. They did have the friendship of William Penn, so it is possible that they had wealthy relatives. The Antrim meetings were held at Ballynacree and sometimes at Toberhead at the McCool family home. Anyway, this is getting off-topic, via DNA I believe the Quaker families of Lightfoot, Holmes, Blackburn and McKee are connected somewhere to the Guilers.
