[2] In 1077 Nigel fought against the Welsh at the Battle of Rhuddlan,[3] as part of the Earl's campaign to conquer North Wales, the mountainous terrain to the west of Chester.
[5] In 1115 he founded Runcorn Priory of the Augustinian Order of Canons Regular,[6] 1.5 miles west of Halton (which his son later moved to Norton), which the foundation charter states to have been done at the suggestion of Robert de Limesey, Bishop of Chester, and with the consent of Richard d'Avranches, 2nd Earl of Chester (1094–1120).
The move was done "at the request and on the advice of" Roger de Clinton, Bishop of Lichfield and Coventry (whose diocese then covered Chester), probably to provide the canons with a larger and healthier site.
[9] He died in Normandy,[10] without issue, when his titles and offices passed to his brother-in-law Eustace fitz John, husband of his sister Agnes.
From about 1144 he became one of the main followers of Ranulf de Gernon, 4th Earl of Chester (1099–1153), from whom he gained much land.
Historical records refer to him as 'John, Constable of Chester';[19] He founded Stanlow Abbey, a Cistercian abbey[10] situated on Stanlow Point, on the banks of the River Mersey in Cheshire, near today's Ellesmere Port, 11 km north of Chester Castle and 12 km south-west of Halton.
[citation needed] Roger de Lacy's son and heir was John de Lacy, 2nd Earl of Lincoln (c. 1192-1240) 8th Baron of Halton, 8th Constable of Chester, feudal baron of Pontefract.
By his first wife Margaret Longespée he had an only daughter and heiress Alice de Lacy, 4th Countess of Lincoln.
Alice de Lacy, 4th Countess of Lincoln (1270–1348) was the daughter and sole heiress of the 4th Earl, her two brothers having died in childhood.
On her death without children her titles became extinct and many of her estates passed to Thomas's heirs the Earls and Dukes of Lancaster.
