From The Ancient Crosses of Lancashire by Henry Taylor:
These words occur on the 1848 six-inch ordnance map close to some old cottages, about one hundred yards to the north of the church. They have recently been pulled down. The well, when I saw it (in April, 1900), was a walled-in dipping well, on the east side of the lane, running due north from Huyton village. It does not appear to be known why the well has its present designation, but Baines states that two chantries were founded here, the first by John de Winwick, rector of Wigan, in 1350 (dedicated to the Virgin); the other by his brother, Richard de Winwick, rector of Walton-on-the-Hill (dedicated to S. Michael the Archangel). Possibly, chantry priests lived in the cottages.
