Grelly History, Family Crest & Coats of Arms
The Grelly surname was most likely originally created from a place name. There is a Gresley in Derbyshire and a Greasley in Nottinghamshire, both of which became habitation surnames. The two place names are in turn derived from the Old English "greosn," or "gravel," and "leah," meaning a "wood" or "clearing."
Early Origins of the Grelly family
The surname Grelly was first found in Derbyshire at Church Gresley or Castle Gresley which date back to c. 1125 when the were collectively listed as Gresele. Later years saw the place name evolve to Castelgresele in 1252 and later as Churchegreseleye in 1363. It is generally thought that the root Gresley was derived from the Old English word "greosn," which meant "gravel." 
As far as the surname goes, the Topographer of 1789 states "In point of stationary antiquity hardly any families in the kingdom can compare with the Gresleys." They are the only family in the county that trace back "to the house of Drakelow; descended from Nigel, mentioned in the Domesday, called de Stafford, and said to have been a younger son of Roger de Toni, standard-bearer in Normandy, it was very soon after the Conquest established in Derbyshire, first at Gresley, and immediately afterwards at Drakelow, in the same parish." 
One of the first records of the name was Sir Thomas de Grelly, who was knighted by King Edward 1st in 1306, and later Baron Gresly who was summoned to Parliament in 1308.
"The manor of 'Lulletune' [Lullington, Derbyshire] was in the Gresley family, in the reign of Edward I.; and the church was given by that family to the priory of Gresley, in the reign of Edward II." 
Childwall Manor in Lancashire "was given to Albert Grelley, Baron of Manchester, and in his successors the superior lordship of the manor continued to be vested. It is recorded among the members of the barony down to 1473. In 1306 Thomas Grelley demanded against Adam de Ireland and Avina his wife two messuages and an oxgang of land in Garston."

Grelly Spelling Variations
Multitudes of spelling variations are a hallmark of Anglo Norman names. Most of these names evolved in the 11th and 12th century, in the time after the Normans introduced their own Norman French language into a country where Old and Middle English had no spelling rules and the languages of the court were French and Latin. To make matters worse, medieval scribes spelled words according to sound, so names frequently appeared differently in the various documents in which they were recorded. The name was spelled Greasley, Gresley, Grysley, Grisle, Grysely, Grisley, Grelly, Gresly, Greseley, Greiseley, Grelley and many more.
Early Notables of the Grelly family (pre 1700)

Migration of the Grelly family
Because of this political and religious unrest within English society, many people decided to immigrate to the colonies. Families left for Ireland, North America, and Australia in enormous numbers, traveling at high cost in extremely inhospitable conditions. The New World in particular was a desirable destination, but the long voyage caused many to arrive sick and starving. Those who made it, though, were welcomed by opportunities far greater than they had known at home in England. Many of these families went on to make important contributions to the emerging nations of Canada and the United States. Analysis of immigration records indicates that some of the first North American immigrants bore the name Grelly or a variant listed above: Jeffery Gresley, who arrived in Virginia in 1791; as well as Philip J Greaseley, who was naturalized in Fairfield Co. Ohio in 1833.
