Hammack History, Family Crest & Coats of Arms
The rich and ancient history of the Hammack family name dates back to the time of the Anglo-Saxon tribes of Britain. It comes from Hamon, an Old French personal name brought to England after the Norman Conquest in 1066.
"The name appears in Normandy during the following century as a surname, for Geoffrey, Ranulph, Waleran, Richard, and Stephen Hamon or Hammon are found on the Exchequer Rolls of the Duchy in 1180-98; and, as Hammond, became common in England. The last Abbot of Battle was a Hammond." 
Early Origins of the Hammack family
The surname Hammack was first found in Kent. The Roll of Battle Abbey reveals that two brothers, sons or grandsons of Hamon Dentatus accompanied the Conqueror in his Conquest. The first was Robert Fitz-Hamon, the renowned Conqueror of Glamorganshire and the second was Haimon, named in the Domesday Book as "Dapifer," for having received the office of Lord Steward for the King. The latter died issueless while the former had four daughters, three of which had conventual lives. 
The remaining daughter named Mabel married Robert Fitzroy, Earl of Gloucester. Hamon Dentatus had two other sons: Richard of Granville; and Creuquer who inherited the Barony of Chatham from Robert Fitz-Hamon and many of the Kentish estates of Hamon Dapifer. 
These estates were passed down to Haimon de Crévequer (died 1208) who had one son Robert Haimon. The latter joined the confederacy of Barons against Henry III., and as a consequence lost all his estates.
Later, West-Acre in Norfolk was home to a branch of the family. "It is the property of A. Hamond, Esq., whose seat here, High House, is a handsome mansion in the Italian style, finely situated in a well-wooded park. The church is partly in the early and partly in the later English style, with a square embattled tower, and contains the mausoleum of the Hamond family, and many beautiful monuments to several of its members."

Migration of the Hammack family to Ireland
Some of the Hammack family moved to Ireland, but this topic is not covered in this excerpt.
Families began migrating abroad in enormous numbers because of the political and religious discontent in England. Often faced with persecution and starvation in England, the possibilities of the New World attracted many English people. Although the ocean trips took many lives, those who did get to North America were instrumental in building the necessary groundwork for what would become for new powerful nations. Among the first immigrants of the name Hammack, or a variant listed above to cross the Atlantic and come to North America were :

Emigration to New Zealand followed in the footsteps of the European explorers, such as Captain Cook (1769-70): first came sealers, whalers, missionaries, and traders. By 1838, the British New Zealand Company had begun buying land from the Maori tribes, and selling it to settlers, and, after the Treaty of Waitangi in 1840, many British families set out on the arduous six month journey from Britain to Aotearoa to start a new life. Early immigrants include:

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: Per tot discrimina verun
Motto Translation: Through so many dangers
