 In this book, the Mac Cana line along with other surname lines are taken right back to Adam and Eve.Due to anglicization and Ulster migration the original form "Mac Cana" has had many different variations, such as McGann, McCann, MacCann, MacCan, Maccan (this part of the Maccans had connections with many European noble and royal families, such as the Maccan Romanoff or the Maccan of Villanova or Maccan de Gueldre), MacCana and Canny.The name became McGann upon Ulster migration to Connaught and became Canny and Canney upon Ulster migration to the south (Leinster and Munster).
