I'm no expert but to me, "O" & "MAC" preceed Irish names. Never lose faith. It's difficult to keep the faith. Even myself I get discouraged & think ... "i'm never gonna get my answer" ... but someday somebody will write & lead you to the right place. It'll all fall-into-place & you'll say "OH I SEE ... NOW IT ALL MAKES SENSE". DNA testing is a good idea. I'm awaiting the results of a DNA test too & am hoping to learn more about how to use the markers of the DNA test to compare to particular surnames.
