Sidney was born in Wolverhampton on 25 January 1897, the son of Albert and Amy Bowyer. They were living at 66 Knox Road in 1901, and by 1911, they were living at 18B Hall Street, Blakenhall, together with Sidney’s siblings Albert, Thomas, Harry, Elsie, Hilda, Ernest and Amy. Sidney was a printer’s errand boy.
On 6 May 1915, Sidney enlisted in the 2nd/6th South Staffordshire Regiment (number 4139), when his trade was given as “bobber”. By 10 May 1916, he was discharged as he was unfit for further military service, having not yet served overseas. By this date, his address was given as 11 Hospital Street, Wolverhampton. He was described as having “poor physique” and debility”, which was neither the result of, nor aggravated by, military service. By the time of his discharge he had not done any training for the previous three months.
On 10 February 1919 he married Dora Hayes at Dudley. He was reengaged in the Territorial Forces on 6 May 1920, with the South Staffordshire Regiment (number 4904177). His trade was now a “fitter”. He served for seven years. Sidney died in Wolverhampton in 1940.
