Hattam History, Family Crest & Coats of Arms
Hattam is a name that came to England in the 11th century wave of migration that was set off by the Norman Conquest of 1066. The Hattam family lived in Hatton, Cheshire. Another derivation of the name suggests that it comes from the Germanic personal name Hatto, which is composed of the element hadu, which means strife or contention.  Although both are valid, time has confused the two definitions and historians now disagree on which is valid in any individual case.
Early Origins of the Hattam family
The surname Hattam was first found in Cheshire where this "noble family were descended from Sir Adam Hatton, of Hatton, county Cheshire, grandson of Wulfrid, brother of Nigel, who was lord of Halton in the same county, by gift of Hugh Lupus, Earl of Chester, soon after the Conquest."

Migration of the Hattam family to Ireland
Some of the Hattam family moved to Ireland, but this topic is not covered in this excerpt.
For many English families, the social climate in England was oppressive and lacked opportunity for change. For such families, the shores of Ireland, Australia, and the New World beckoned. They left their homeland at great expense in ships that were overcrowded and full of disease. Many arrived after the long voyage sick, starving, and without a penny. But even those were greeted with greater opportunity than they could have experienced back home. Numerous English settlers who arrived in the United States and Canada at this time went on to make important contributions to the developing cultures of those countries. Many of those families went on to make significant contributions to the rapidly developing colonies in which they settled. Early North American records indicate many people bearing the name Hattam were among those contributors:

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.
Motto: Nil conscire sibi
Motto Translation: To have a conscience free from guilt.
