Gadly History, Family Crest & Coats of Arms
The ancestors of the Gadly surname lived among the ancient Anglo-Saxon culture. The name comes from when they lived in Hadleigh or Hadley, a place-name found in numerous locations in England. The root of these names is common, however; they are all derived from the Old English roots hæth and leah, which taken together mean "forest clearing where the heather grows." 
Early Origins of the Gadly family
The surname Gadly was first found in Essex at Hadleigh, a parish, in the union and hundred of Rochford. 
Over in Suffolk, Hadleigh was a market-town and parish, in the union and hundred of Cosford. "This town, which was probably founded during the heptarchy, about which period a monastery is said to have been established by one of the Saxon kings, was called by the Anglo-Saxons Headlege, whence it derived its modern name. Some of the kings of East Anglia were interred here; as also was Guthrum, or Gormo, a Danish chief, who submitted to Alfred the Great, and renounced paganism after the defeat of the Danes at the battle of Ethandune, now Eddington, in the county of Wilts: a tomb is still shown in the church as the monument of Guthrum (who died in 889)" 
"In Essex and Suffolk I find two parishes of Hadleigh, and in Middlesex a parish Hadley."  Another source notes: "Hædleáh in an Anglo-Saxon will of the 10th century." 
The first record of the family was indeed found in Suffolk. Matilda de Hadlega was listed there in the Pipe Rolls of 1194. Warin de Hadlai was listed in the Pipe Rolls of Yorkshire in 1212 and John Hadley was listed in the Feet of Fines for Essex in 1390.

Migration of the Gadly family
A great wave of immigration to the New World was the result of the enormous political and religious disarray that struck England at that time. Families left for the New World in extremely large numbers. The long journey was the end of many immigrants and many more arrived sick and starving. Still, those who made it were rewarded with an opportunity far greater than they had known at home in England. These emigrant families went on to make significant contributions to these emerging colonies in which they settled. Some of the first North American settlers carried this name or one of its variants: George Hadley settled in Salem Massachusetts in 1630; David and John Hadley settled in Virginia in 1772; Martha Hadley arrived in Maryland in 1736; Mrs. R. Hadley arrived in San Francisco with her child in 1860..
