Hello! A DNA test I took recently is showing that my Callahan ancestors were probably from Clonca Parish, but they lived before the parish records seem to have survivied, and immigrated about 1821 to Delaware, USA.
Patrick Callahan born about 1773 had children:
-Michael Callahan b.3/15/1812
-Denis Callahan b.c.1805
-Jeremiah Callahan b.c.1822
-Patrick Callahan b.c.1917
-Darby Callahan b.c.1811
-Neil Callahan
Where should I look next?
