Harker History, Family Crest & Coats of Arms
The ancestors of the Harker family brought their name to England in the wave of migration after the Norman Conquest of 1066. They lived in Oxfordshire. Their name, however, refers not to this location, but to the family's place of residence prior to the Norman Conquest of England in 1066: one of two towns, Harcourt, in Calvados, Normandy, or Harcourt in Eure, Normandy. 
Another source provides more detail: "A town and ancient chateau, now in ruins, near Brionne in Normandy, which gave title to the French Ducs de Harcourt. The ancient earls of Harcourt played a distinguished part in the history of Normandy. They were descended from Bernard, of the blood-royal of Saxony, who having been born in Denmark was surnamed the Dane. He was chief counsellor and second in command to Rollo at the invasion of Neustria in A.D. 876, and acquired Harcourt and other fiefs for his eminent services." 
"Robert de Harcourt attended William I. to the Conquest of England, and his descendants possessed Stanton-Harcourt, co. Oxon, from 1166 to 1830, when the elder line became extinct." 
Early Origins of the Harker family
The surname Harker was first found in Oxfordshire. Errand de Harcourt who claimed descent from Bernard the Dane, who was granted the Lordship of Harcourt from Rollo of Normandy in 876 commanded the Archers of Vel de Ruel in the Conqueror's army. Rather than staying with his fellow countrymen in the newly conquered country, he returned to Normandy shortly after William's coronation. His younger Robert who had also accompanied him on the Conquest remained. Robert's son, William de Harcourt, a strong supporter of Henry I., commanded the troops that defeated the Earl of Mellentin in 1123. In return for his noble efforts, he received many more lands in England. 
Some of the early notables of the family include: Philippe d'Harcourt (died 1163), Chancellor of England (1139-1140); Louis d'Harcourt (died 1388), Vicomte de Châtellerault, Governor and Lieutenant Général of Normandy (1356-1360); Jacques I d'Harcourt (1350-1405), Baron of Montgommery, Councillor and Chamberlain of king Charles VI; Jacques II d'Harcourt (died 1428), Comte de Tancarville, Governor and Lieutenant Général of Picardie; Christophe d'Harcourt (died 1438), Lord of Havré, Councillor and Chamberlain of King Charles VII, grand-master of the waters and the forests; Guillaume d'Harcourt (died 1487), Comte de Tancarville, Ccounsellor and Chamberlain of King Charles VII, Constable and Chamberlain of Normandy, grand-master of the waters and the forests (1431).
This was the beginning of one of the most noble families in England that would quickly rise to the status of the House of Harcourt from which Simon, Lord Harcourt would become Lord Chancellor temp. Queen Anne.
Over in the parish of Wyrardisbury in Buckinghamshire, a more recent member of the family holds a piece of history. "Within its limits is Magna Charta island, a small islet in the Thames, on which King John, at the instance of the barons, is said by some to have signed the celebrated charter of English liberty; it is the property of G. Simon Harcourt, Esq., of Ankerwycke House, in the parish." 
William de Harewcurt was listed as an Old English Byname in 1055 and later, Philip de Harecourt was a Knights Templar in Sussex in 1139.

Early Notables of the Harker family (pre 1700)
Outstanding amongst the family at this time was Field Marshall Harcourt; and Sir Simon Harcourt, who was Lord Chancellor of England during the reign of George the I (1714-1727).
Robert Harcourt (1574?-1631), was an English traveller, born about 1574 at Ellenhall, Staffordshire, was the eldest son of Sir Walter Harcourt of that place and Stanton Harcourt, Oxfordshire.

The unstable environment in England at this time caused numerous families to board ships and leave in search of opportunity and freedom from persecution abroad in places like Ireland, Australia, and particularly the New World. The voyage was extremely difficult, however, and only taken at great expense. The cramped conditions and unsanitary nature of the vessels caused many to arrive diseased and starving, not to mention destitute from the enormous cost. Still opportunity in the emerging nations of Canada and the United States was far greater than at home and many went on to make important contributions to the cultures of their adopted countries. An examination of many early immigration records reveals that people bearing the name Harker arrived in North America very early:

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: Le bon temps viendra
Motto Translation: The prosperous time will come.
