Owen Callen / Courtney
After searching for 52 years, (since 1962) I finally discovered the home farm for my immigrant ancestor, Owen Callen / Courtney in the Townland of Doora, Donaghmoyne Parish, County Monaghan, Ireland.
What is strange is that the surname kept bouncing back and forth between Callen and Courtney, both in Ireland and after they immigrated to New York State in 1847.
Most Courtneys in Ireland are genetically Irish, meaning that their name Courtney (which is English) is an anglicized version of a Gaelic name. Some Irish names that have made this change are Cournane of County Kerry, Callan/Callen of County Monaghan, and McCourt of County Louth.
