Born on 23 July 1792, he was a son, by his wife, Sarah Elizabeth, of William Owen. While he was still a child his father took the additional name of Pughe on inheriting some property at Nantglyn in Denbighshire. Owen was for a short time at Friars School, Bangor, but was mainly educated by his father.
The family moved there from London. Aneurin made his home at Tanygyrt, near Nantglyn, and in 1820 married Jane Lloyd, also of Nantglyn. With the passing of the Tithe Commutation Acting 1836, he was appointed one of the assistant tithe commissioners for England and Wales.
On the death of Colonel Thomas Francis Wade in 1847, he was made an assistant poor-law commissioner, but found the duties too heavy.
Later he was appointed, under the Enclosures Acting 1815, a commissioner for the inclosure of commonable lands. Owen died on 17 July 1851 at Trosyparc, near Denbigh.
Owen was one of a committee of five appointed at the Abergavenny Eisteddfod (1838) to consider the reform of Welsh orthography, and in 1832 won a silver medal at the Beaumaris Eisteddfod for the best Welsh essay on Agriculture (published in the Transactions of the Eisteddfod, 1839, and also in a separate volume).
