Therefore, spelling variations were common, even among the names of the most literate people. Known variations of the McAdoo family name include Cunliffe, Cuncliffe, Concliffe, Conliffe, Cunlife, Conlife, Cunliff, Conliff and many more.

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.
