Administrative / Biographical History

The Ynysymaengwyn estate was owned by the Wynnes until the death of Humphrey Wynne (alive in 1570) when the estate passed to his daughter Elizabeth who married Sir James Pryse of Gogerddan, Cardiganshire. Their sole heiress was Bridgett Pryse who in or around 1612 married Robert Corbet of Moreton Corbet, Shropshire. The eldest son and heir of this marriage was Vincent Corbett who apparently disinherited his son Thomas Vincent Corbett so that the estate passed to his sisters Ann, who married Athelstan Owen of Rhiwsaeson, Montgomeryshire, and Jane who married, firstly, Thomas Price of Esgairweddan and, secondly, Hugh Wynn, rector of Dolgellau. There were no heirs from either of Jane's marriages. A year before her death, Ann Owen settled the Ynysymaengwyn estate, which by now included the Caethle estate in Tywyn which Ann herself had purchased from Richard Braithwaite and Margaret his wife, to her second son Richard Owen, Corbett Owen her eldest son having already died without issue. Richard Owen also died without issue so that the estate devolved upon his sister Ann Owen. She married Pryce Maurice, owner of the Lloran estate, Denbighshire, in 1740. In accordance with the terms of a deed of settlement of 1758 and the will of Ann Owen the estate passed to Ann Owen's grandson, Henry Arthur Maurice, that is the third son of the marriage of her daughter and namesake and Pryce Maurice. Henry assumed the name of Corbet on inheriting the Ynysymaengwyn estate. He died aged 30 in 1782 and was succeeded by his brother Edward Maurice. He likewise assumed the name Corbett. Following his death in 1820 the estate passed to his nephew Athelstan Maurice, who also assumed the name Corbett. He died in 1835 and was succeeded by his daughter Henrietta and her husband John Soden of Bath who likewise assumed the name of Corbett. His son, a deeply indebted Athelstan John Soden Corbett, finally decided to sell the estate, which measured 9,347 in 1873. The entire estate was sold between 1877 and 1879, the main purchaser being John Corbett, MP, (no relation) of Droitwich, Worcestershire, who bought Ynysymaengwyn mansion, demesne and pleasure grounds for £42,000.
