William de Warenne was granted vast land holdings for his part in the Norman invasion, including Harthill manor.
[4] Thomas Osborne, 1st Duke of Leeds (1632–1712) purchased the Harthill estate while Earl of Danby, and had a fine mortuary chapel built in the north-east corner of All Hallows Church.
Over it, in semi darkness, hangs a dusky display of armour, a very beautiful shield is embossed metal, some faded banners, and a Civil War standard.
The almost concealed window contains shields exhibiting the marriages of his large family, executed in painted glass by W. Price in 1705.
"[5] The statue of Lady Margaret Osborne (née Belasyse, who died comfortably in 1624) kneels at a desk with one child behind her and another in swaddling clothes.
Twenty four coffins, most of them retaining their red plush covering, brass-head nails, and sheet-brass coronets, are laid on the stone-wall bench and an iron table.
