Haddly History, Family Crest & Coats of Arms
The ancestry of the name Haddly dates from the ancient Anglo-Saxon culture of Britain. It comes from when the family 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 Haddly family
The surname Haddly 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 Haddly family
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. Some of the first immigrants to cross the Atlantic and come to North America bore the name Haddly, or a variant listed above: 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..
