FindMyPast (www.findmypast.co.uk) have just released some RAF service records (1912 – 1939). I found my paternal grandfather’s records. He was in the Royal Navy Air Services in 1916 and this merged with the Royal Flying Corps in 1918 to become the Royal Air Force. He joined the RAF reserves in 1919 and this is the last entry.
For info the number of entries for these RAF service records for the one name study split as:
Baughan 6
Baughen 3
Baugham 1
Bangham 1
Baffin 1
Boffin 1
