Henderson - Gunn Genetic Connections: The Missing Link

Part of our research into family history has been to use DNA to look beyond where the stories stop and into the deeper ancestry of the Hendersons of Caithness. The human Y chromosome is passed unaltered from father to son, with a few mutations creeping in ever several generations or so. An emerging field of research has been to connect families based on similarities in their Y chromosomes – if the DNA matches closely, they are related.

For my Henderson family, this has presented a historical puzzle. The history of Caithness describes the sundering of the Gunn clan following the battle of St. Tears, and how Henry Gunn and his family decided to part ways with their kin and took the surname Henderson. If history is correct, my DNA should match the DNA of someone in the Gunn family. However, that has not been the case, even when we were able to test the DNA of a Gunn with confirmed Ramscraigs heritage.

Several weeks ago, as a result of this web site, a fellow in Canada by the name of Henderson contacted me via email. A very pleasant gentleman, we carried on an good conversation over email, and eventually it came to light that his family emigrated to Canada, living in Nova Scotia and Manitoba. To me, this was an immediate attention grabber. Many displaced families from Caithness and Sutherland had joined the Selkirk settlement in Manitoba and the Red River valley.

His roots to Scotland included an ancestor from Kildonan who lived in Helmsdale before shipping over to Canada. This is the same path that many Hendersons and Gunns had taken during the period of the clearances, and his family line would hold many possible points of history.

Fortunately, he had his DNA tested some time ago, though it was not even remotely close to mine. Instead, an interesting thing arose. The Gunn who helped us out so much by offering his DNA for testing was a very close match, close enough in fact that the most recent common ancestor was likely in the 500-700 year time frame.

At long last, here was DNA science proving the connection between the Gunns and the Hendersons. This man, whose family was forced from Kildonan (the last stronghold of the Gunn clan), carried with him the Gunn DNA fingerprint. He had realized this himself some time ago, but had met with rejection and confusion from the Gunn clan association. For many of Clan Henderson USA, his genetics are a breakthrough in history. Many members of their genetics project have lost their connection to Scotland through the decay of time. But with this new DNA sample, many of these are clearly Kildonan Gunn Hendersons who arrived in the colonies either seeking a better life, or after being cleared from the Strath of Kildonan.

For my genetic line, the work to solve the puzzle of a I1d-Norse ancestory goes on.
