expanded in the 18th century, when a forge at Congreve was turning out 120 tons of iron a year, and in the 1820s the mill below Bull Bridge was used for rolling iron. However, this industry tailed off as the Black Country ironworks outstripped it. Extraction of building materials grew in Victorian times, with the Littletons operating quarries at Wolgarston, Wood Bank, and Quarry Heath, as well as a sand pit at Hungry Hill, Teddesley, and a brickyard in Penkridge. Zenith of the Littletons The fortunes of the village and the Littletons remained intertwined. Sir Edward Littleton, the fourth baronet, bought Penkridge manor from the Earl of Warwick in 1749, completing his family's dominance of the area. Soon after he built Teddesley Hall, a much more impressive seat for the family. He survived until 1812, although, his wife died childless in 1781. He adopted his great-nephew, Edward Walhouse, as his heir. Walhouse took the name Littleton and took over the Littleton estates, although not the Littleton baronetcy. He achieved far greater eminence as a politician than any other member of the family, serving as Chief Secretary for Ireland under the Whig Prime Minister Grey in 1833–35. He was elevated to the peerage as Baron Hatherton, a title which remains with the head of the Littleton family to the present, and became an active member of the House of Lords. Hatherton resided at Teddesley, where he established a free agricultural college and farmed successfully. He strongly promoted education in the area, paying for a National School in Penkridge and another at Levedale, and for clothing for some of the school children. However, his lifetime saw a decisive shift in the family's interests. As heir to both the Walhouse family fortune and the Littleton estates, he owned great estates around Penkridge and mineral holdings and much residential property in the Cannock and Walsall areas. He owned coal mines at Great Wyrley, Bloxwich and Walsall; limestone quarries and brickyards in Walsall that were used to build much of the town; hundreds of residential and commercial properties; gravel and sand pits, stone quarries in many places. Unlike Penkridge, Cannock and Walsall were boom towns of the Victorian era, powered by the most modern and profitable industries of the age. The Littletons played a leading part in this phase of the Industrial Revolution and made large profits from it, and this tilted their attention increasingly
