  Burial Notes:

From Wikipedia - Stanlow Abbey :

Stanlow Abbey (or Stanlaw Abbey) was a Cistercian abbey situated on Stanlow Point on the banks of the River Mersey in the Wirral Peninsula , Cheshire , England (grid reference SJ427773 ).

The abbey was founded in 1178 by John FitzRichard , the sixth Baron of Halton .[1] Roger de Lacy , John de Lacy and Edmund de Lacy , respectively the 7th, 8th and 9th Barons of Halton, were buried at Stanlow.[2] The abbey was in an exposed situation near the Mersey estuary and it suffered from a series of disasters. In 1279 it was flooded by water from the Mersey and in 1287 during a fierce storm, its tower collapsed and part of the abbey was destroyed by fire. The monks appealed to the pope for the monastery to be moved to a better site and, with the pope's consent and the agreement of Edward I and Henry de Lacy , the 10th Baron, they moved to Whalley Abbey near Clitheroe , Lancashire .[3] This move took place in 1296.[4][5] However a small cell of monks remained on the site until the Reformation ,[3] the site becoming a grange of Whalley Abbey.[6] The remains of the abbey lie between the Mersey and the Manchester Ship Canal . The standing remains include two sandstone walls and a re-used doorway, and the buried features include part of a drain leading to the River Gowy . These remains are recognised as a scheduled monument .[6]
