The last recorded use was in 1858, when a villager was put in the stocks for six hours after failing to pay a fine for drunkenness.Iron currency bars from the Iron Age have been found. The Roman colonists also worked the ironstone deposits in this area. There were ironworks here in Edward the Confessor's reign in the 11th century, when Gretton was a royal manor. The industry came to the fore again from 1881 to 1980, providing ore for Corby's steel works.Notable people living in Gretton include ultra marathon runner and yeast expert Jim Wynn and marathon runner and primary school teacher Sarah Wynn.
Jim and Sarah Wynn started Gretton's notable Turtle Run Club (TRC) in 2019.
