Hi, I am Greg Corkill from California, U.S.A.. My father was Richard Corkill also from Ca. and my grandfather was Jack Corkill from somewhere in Illinois He was born june 29th 1908. This is where I lose the history. I have no idea what his dad's name was only that he had twin sisters and his dad was a blacksmith. I was told we were from Mann when I was young. I have no living relatives that can shed light on my great-grandfather's name or heritage. Can anyone help?
