Further to the biography which PatLac linked to, based on his regimental number George Albert Taylor joined the South Notts Hussars in the third or fourth week of September 1914. The man with the number 1046 joined on the 15th September and by 12th October number 1408 had been issued. Bert would have been aged just 17 and two months when he joined up. This was legal but he should not have gone overseas until he was 18. In fact he was 4 months short of his 18th birthday when his regiment sailed from Avonmouth in April 1915. It is possible that he lied about his age when he joined, or alternatively his unit were prepared to turn a blind eye to this fact, possibly because they knew they were headed, initially, for Egypt which was not a theatre of operations at the time. Bert was 18 once he arrived with his unit in Suvla Bay (Gallipoli).
Given his connection Nottingham, he is likely to have been in C Squadron South Notts Hussars.
