The Gregson family feature continuously in the story of St. Andrew's church in Dalton-le-dale. Successive generations have been buried in the family vault underneath the 13th century font, which is situated at the west end of the church.
There are also family graves outside the porch entrance near the south door. The Gregson's name features on many furnishings and graveyard inscriptions. In 1566 John Gregson bought his Murton estate from his landlord, Lord Lumley. His grandson John bought Burdon in 1674, the year Parish Records began.
In 1701 John Gregson of Moorton and William Wood of Cold Hesledon were appointed overseers of the poor of Dalden. During the 1907 restoration of the church the Gregson's did some work of their own in the surrounding area. They demolished two farms and replaced them with three rows of terraced houses, namely, Dunelm Terrace, St. Cuthbert's Terrace and St. Andrew's Terrace. The Gregson's contribution to the village and church was vital for their upkeep and survival.
Major Charles Dalton Gregson represented Burdon on Easington's Rural District Council during the 1930's, he died in Tobago in 1953. He had three sons, John the eldest was in the Durham Light infantry and was killed in action just before Dunkirk. Charles Edward died aged fifteen in 1934. The last owner of the estate, Anthony Allgood Moore Gregson, retired from the Royal Artillery as a major in 1958. He had three children, two girls born in 1951 and 1953 respectively and one son born in 1956. The first born son died tragically in Malta from an electric shock.
The Gregson family sold the estate in 1931. Nine of the windows in St. Andrew's are dedicated to members of the family, a fitting epitaph for such a great and supportive family.
