Depends
in reply to a message by Shiply
For other people who would have no idea, it's not a problem. Even if they found out I don't think it would be a problem. It's only an issue if meaning is important to you. I want my children's names to have meanings that I think are important or significant, and the meaning of Cormac wouldn't qualify. Unless someone could ever explain to me how it could have some positive significance. :)
