The surname Delacy comes from the place name Lassi, in the department of Calvados in Normandy.

Early Origins of the Delacy family

The surname Delacy was first found in Yorkshire, where Ibert de Lacy, son of Walter de Lacy (Lacie) was granted the castle and town of Pontefract and 164 lordships by William the Conqueror. Walter de Lacie (d. 1085) was one of the commanders that William the Conqueror "sent to Wales to subjugate the principality; and being victorious, he acquired large possessions there, in addition to those already obtained, as his portion of the spoil of Hastings. " 1

"His lands had been assigned to him in the West, where he held territory - to what exact extent is not known - under William Fitz Osbern, the first Norman Earl of Hereford; and upon the rebellion of William's son, Earl Roger de Britolio, the whole vast fief was conferred upon him by the Conqueror. He waged war successfully with the Welsh, defeating three of their princes with great slaughter in Brecon; and was killed in 1085 by a fall from a ladder while inspecting a new church he had founded at Hereford. " 2

Roger de Laci who also accompanied the Conqueror was rewarded with the tenure in capite of 116 lordships. It is presumed that the two were related but the relationship is unknown. 3

Rishton in Yorkshire was the place where a manor was held by Edmund de Lacye, who died 42nd Henry III. 4

There were at least two listings of the name in the Yorkshire Poll Tax Rolls of 1379: Robertus Lascey; and Isabella Lassy. 5

Stanlow-House in the union of Great Boughton, Higher division of the hundred of Wirrall in Cheshire was an ancient family seat to one branch of the family. "An abbey of Cistercian monks was founded here in 1178, by John Lacy, constable of Chester; but on account of the inundations of the Mersey in 1296, it was removed to Whalley, in Lancashire." 4
