The Herdmans and the model village
James, John, and George Herdman came to Sion Mills in 1835, converted an existing flour mill on the River Mourne into a flax-spinning operation, and then did something most industrial mill owners did not: they built the village their workers would need. Housing, a school, a cricket ground, a football pitch, recreational amenities - the development of Sion Mills was shaped by the same ideas of industrial paternalism that Robert Owen had demonstrated at New Lanark in Scotland. The mill itself grew over the decades, a second and larger building going up in the 1850s, and by the 20th century Herdmans Ltd was one of the significant linen employers in Ulster. The visual coherence of the village today - the half-timbered facades, the Tudor-revival church, the stable block - came from the family's decision in the 1880s to commission English architect William Frederick Unsworth to redesign the entire settlement. Unsworth worked here across three decades, transforming the Herdman family residence into a half-timbered mansion in 1884 and completing the Church of the Good Shepherd in 1907-1909. His last work in Sion Mills was the church; he died in 1912. The family's name still runs through the village - Herdmans Ltd, the cricket club's origins, the mill buildings on the Mourne.
