Administrative / Biographical History

John Glasbrook was a successful colliery owner working collieries such as Beaufort Colliery, Birchrock Coal Company and the Garngoch Collieries. His industrial interests also included the Messrs. John Glasbrook, Sons & Co., Timber Merchants of Swansea, Glasbrook's Brick and Tile Co. of Forestfach and John Glasbrook, Sons and Co., Cambrian Steam Saw Mills, South Dock, importers of timber and slate merchants. When Phillip Richard, co-partner and brother-in-law died in 1878, he took over Morriston Collieries. He purchased Brynmor House in Swansea in 1850, and acquired land on both sides of the Glamorgan/Carmarthenshire border, including farms in the parishes of Llangyfelach, Llandeilo Talybont, Loughor, Swansea, Llandybie and Llanelli. When he died in 1887 he appointed his five sons, Thomas (d. 1892), John, Isaac Thomas [d. c.1912], David Mansell (d. 1933) and Sydney Edward [d. c.1896] joint trustees of his property. They traded together in partnership as colliery proprietors known as Glasbrook Brothers in 1892. In 1898, the Glasbrook Brothers, Limited was incorporated and in 1908, it became a private company. Bryn-y-mor estate was put for sale by auction by W J Rees in 1909. John Glasbrook Sons and Company Limited was wound up voluntarily in 1929. The brothers continued to administer the Messrs Glasbrook Bros Ltd estate until the last brother, David Mansell, died in 1933.
