Yes, Dan. I have done a YDNA test. However the McKennas (or, as they sometimes called themselves, Kennaugh) are related through my wife's family. My daughter has had her atDNA done but no McKenna matches. My wife's Great Grandmother, Mary Catherine McKenna, is a total mystery except that she was somehow connected to the McKennas of Vernon River, PEI. No luck so far tracing her.
