I've been researching my father (William Phillips)'s life and, in particular, his service in WW2 but have reached an apparent contradiction. His family home was in Ferndale in the Rhondda. In 1936, he enrolled for 3 years at Caerleon College in Newport to train as a teacher and he took digs with a family in Cardiff. He told me that he volunteered to do his 2 years National Service as soon as he qualified so that there wouldn't be a subsequent break in his teaching career but that war broke out whilst he was doing his service so he was in for the duration. However, now that I have his Army Service Records there's an apparent contradiction. The copy of his 1939 National Register entry that I obtained from Ancestry (attached), which I understand was taken at the end of September 1939, clearly shows him at the same address in Cardiff and described as a University Student. [I thought this was strange because his 3 year college course would surely have finished around May or June of 1939]. His Army Service Record shows him enlisting in July 1939 and, on 01 September 1939, being assigned to a searchlight battery at Kinmel near Rhyl in North Wales. Can anyone shed any light on whether or not the 1939 National Register was undertaken earlier than September in Wales or whether there was a similar 'census' taken around 1938-39 which Ancestry may be posting as the 1939 National Register? I'm confused. Thanks in advance for any help or advice.
