Previously, it was believed that the families of Corkill and Kinley were descended from a Scandinavian ancestor. This is now known to be wrong. They are descended from an ancestor in Cork Ireland (dna SNP A11115) whose ancestry goes back through southern England, (dna SNP PF4135) Doggerland (dna SNP Y12072), Netherlands (dna SNP S2639), and back to the founding of dna SNP L161 in Germany, Moldova, Poland or Ukraine about 13,000 years ago. Scandinavia is not a part of this history.

A11115 was founded about 1850 years ago, 150 AD. They stayed in Cork for quite a while allowing time for about four more SNPs to evolve. Then a man who had all these SNPs moved north, arriving in IoM maybe around 1000 AD. Not long afterward, say 1200 AD, surnames were being adopted and inherited. Two of this man's descendants took up separate surnames: Kinley and Corkill. It is not known why the names were different nor why they were chosen.
