These names are also in my line but way back in the 1700's. I am looking for the connection between:
William Erwin, born in Ireland before 1711 and died December, 1774 in York Co, Cumberland Twp, PA and
Colonel Arthur Erwin, born in Ireland in 1726 and died June, 1791 in Tioga Point, Luzerne, PA
Colonel Arthur's father was Joseph Erwin (Irvine). Between 1650 and 1690 Joseph lived in Ballynedrentich, Killead Parish, County Antrim, Northern Ireland. He died there in 1771. I have a hunch that Joseph may have been a brother to my William Erwin. William also had a brother named James who lived next door to William in York County, Cumberland Twp, PA prior to William's death in 1774.
My brother has joined the Family Tree DNA study for the ClanIrwin project. He has matched closest to those who descend from Colonel Arthur Erwin. I know my tree from William on down to me and there is no way that we connect to Colonel Arthur below William.
Therefore since William is about the same age as Joseph I was wondering if Joseph had brothers William and James. Please, if any one has any information about this possible connection, contact me.
