Ambross History, Family Crest & Coats of Arms
The name Ambross was brought to England in the great wave of migration following the Norman Conquest of 1066. It comes from the medieval given name Ambrose, which was in turn derived from the Latin Ambrosius, which means immortal.   
The name Ambrose was extremely popular and spread rapidly because of devotion to Saint Ambrose, who lived during the 4th century and was one of the four Fathers of the Western Christian church.
Some say that this name is descended from the Greek, meaning "immortal or divine," but it is more likely that the name is Norman and is taken from one of the great fathers of the Latin Church. Pierre de Ambroise was the Seigneur of Chaumont in Normandy and was living in 1440, apparently the surviving Norman branch of the family name. This family intermarried with the descendants of King Charles VII of France and is directly descended from Jacqueline, the King's mistress.
"No doubt the fair amount of popularity obtained in England for this fontal name was due to the great St. Ambrose, Archbishop of Milan." 
Early Origins of the Ambross family
The surname Ambross was first found in Norfolk where the Latin form Ambrosius was recorded 1168-1175 at Holme. 
Almost one hundred years later, the Hundredorum Rolls of 1273 included many different early spelling throughout ancient Britain: William Ambroys, Bedfordshire; Robert Ambros , Huntingdonshire; Richard Ambrosie, Huntingdonshire; and Henry Ambreis, Oxfordshire. 
Later, William Ambroys was recorded in the Subsidy Rolls for Sussex in 1332. 
Later in Scotland, "William Ambrosij (gen.) was burgess of Glasgow in 1488; and in 1499 a payment of eight bolls of wheat was made to Alexander Ambrose and his wife. Alexander Ambroise was minister at Newbotle, 1609. John Ambrose of Graystain was charged with assault in 1628, Jean Ambrois was a resident in Dunkeld in 1675, and four individuals of this name are recorded in Edinburgh in the seventeenth century."

Ambross Spelling Variations
A multitude of spelling variations characterize Norman surnames. Many variations occurred because Old and Middle English lacked any definite spelling rules. The introduction of Norman French to England also had a pronounced effect, as did the court languages of Latin and French. Therefore, one person was often referred to by several different spellings in a single lifetime. The various spellings include Ambroase, Ambrose, Ambross, Ambroyse, Ambrusious, Ambrusius, Ambros, Ambroise, Ambrorrows, Ambroroughs, Ambury, Amburys, Amborows, Ambroraes, Ambesace, MacAmbrose, McAmbrose and many more.

Migration of the Ambross family to Ireland
Some of the Ambross family moved to Ireland, but this topic is not covered in this excerpt.
Many English families left England, to avoid the chaos of their homeland and migrated to the many British colonies abroad. Although the conditions on the ships were extremely cramped, and some travelers arrived diseased, starving, and destitute, once in the colonies, many of the families prospered and made valuable contributions to the cultures of what would become the United States and Canada. Research into the origins of individual families in North America has revealed records of the immigration of a number of people bearing the name Ambross or a variant listed above:
