London, marriage & children
In London, Oswald played football for London Welsh: "On Saturday last Oswald Owen who has recently left Llanidloes for London appeared on the left wing for the London Welsh in their English Amateur Cup Tie with Hounslow on the latter's ground. The Welshmen won by 4 to 2. The Morning Leader of Wednesday, commenting on the game, said Owen gave a very creditable display, and is an acquisition to the team. The third goal was obtained by Owen." [Ibid. 22 Oct. 1898] A year later the newspaper reported: "Mr J Oswald Owen, formerly assistant master at the National Schools, has been appointed to a similar post at Westbourne Higher Grade School, Westbourne Park, London, W. There were many applications for the post." [Ibid. 28 Oct. 1899]
For many years Oswald returned to Llanidloes in the holidays and occasionally played for his old cricket and football teams; on Boxing Day, 1900, he "played a splendid [football] game for the homesters, and the goal he scored was one of the finest efforts seen on the home enclosure" [Ibid. 29 Dec. 1900]. In 1909 he was in Llanidloes to help out with the August Bank Holiday sports events. In 1905 he had been best man at the Llanidloes wedding of his brother James.
Oswald himself had married on Christmas Eve 1904 at St Luke, Hammersmith, Mary Fynn, born in New Cross, Surrey, [Camberwell 1876, 3rd qt], the daughter of an engine smith/engineer, John Fynn. Mary was listed as 'Mary May' on one Electoral Register, and I believe she was known as 'May'. By 1901 she was living with her family at 97 Coningham Road, Hammersmith. Oswald and May's first child, Mary Dorothy Owen, was born on 11 November 1906. They may have lost children; their surviving son, (Oswald James) Morgan Owen, Known as 'Morgan', was not born until 14 February 1915; he and his sister were christened at St Luke, Shepherds Bush.
