Known as "Fair Edith" she held manors in this part of Buckinghamshire, including a hunting lodge at Mentmore.
At least one member went on the crusades, and had associations with the Hospitallers, the organization credited with rebuilding Quainton church circa 1340.
The church contains many memorial brasses and sculpture, including the 1689 tomb of Sir Richard Winwood carved by Thomas Stayner.
The stone effigies depict the deceased lying in full armour, while his widow, Ann, who paid for the tomb, rests beside him, half sitting regarding her husband.
Richard Brett, a former rector of Quainton and one of the translators of the King James Version of the Bible, is buried in the chancel.
The Winwood Almshouses, still inhabited, were built to house the poor, their gothic style of architecture belying the construction date of 1687.
Quainton's nearest National Rail station is Aylesbury Vale Parkway, about 5 miles away.
Passenger services ceased in 1963, but trains from Aylesbury run to connect with events at the Buckinghamshire Railway Centre at Quainton Road station on some Bank Holidays.
