Arthur Owen Vaughan
Lt. Colonel Arthur Owen Vaughan DSO OBE DCM (6 September 1863 – 15 October 1919), also known by his bardic name Owen Rhoscomyl, was an English-born writer, soldier and Welsh nationalist. Born as Robert Scourfield Mills in England, Owen Rhoscomyl was influenced by his Welsh grandmother and became a notable patriot to Wales and its history.
Vaughan was born in Southport, Merseyside but moved to Lancashire where he was raised. As a child, Vaughan was highly influenced by his maternal grandmother, who was born in Tremeirchion in North Wales. At the age of 15 he ran away from home and went to sea, travelling to America. There he became a cowboy and found work in mining camps before returning to Britain.
In 1887 he joined the 1st Royal Dragoons. He left the Royal Dragoons in 1890 but was soon back serving the British Army in the Boer War of 1899–1902. Vaughan served in several horse troops, mainly  in Rimington's Guides and after they disbanded in 1901, their successor unit Damant's Horse. While in this unit, Vaughan was cited for bravery under fire and earned a DCM. In October 1901 he joined Ross's Canadian Scouts, an anti-commando outfit previously led by A. L. Howard, in which Vaughan reached the rank of captain. While in South Africa, Vaughan met and married Catherine Geere secretly in December 1901.
On his return to Britain in 1902, Vaughan set out to promote Wales and in 1905 he completed his most famous work Flame-Bearers of Welsh History: Being the outline of the Sons of Cunedda, which looked at the contribution of the Welsh to the growth of the British Empire. In 1906 he wrote the novel Old Fireproof, followed by Vronina (1906) and Lone Tree Lode (1913).
He and Catherine had four children. Catherine died in 1927, while Vaughan died in 1919. Following Vaughan's death, a fund was raised to provide a memorial for his grave in honour of his Welsh patriotism in Rhyl, Flintshire. Two headstones mark his grave: the usual marble headstone for British soldiers under his own name, Lt Col A.O. Vaughan, and a Celtic cross honouring his achievements for the Welsh  under his bardic name Owen Roscomyl.
