Ralph Cromwell (1393-1456) was born in Lambley and became a great statesman of the period, having fought with King Henry V at Agincourt and becoming Lord Treasurer to Henry VI. Cromwell’s badge of office, a bulging purse, can be seen on the stone panels on both sides of the window in the east wall of the parish church. A legacy left by him financed the rebuilding of the church, which was rededicated in 1480 as the church of the Holy and Undivided Trinity. He was also the builder of Tatershall Castle, Lincolnshire; one of the countries earliest brick built properties.

Nell Gwynn: The popular story is that Charles II and his guests, when staying at Bestwood lodge, would tease poor Nell for sleeping in and missing a good morning’s sport. Charles II offered to gift to Nell, “All the land she could ride around before breakfast,” and was surprised the next day to find Nell sitting for breakfast before the King and all the guests. It was claimed she had ridden out early, dropping handkerchiefs along her route, and the encircled area became Bestwood Park. True to his word Bestwood Lodge and park were handed over to Nell and her descendants – The Dukes of St Albans
