In the 1946 London Electoral Register on Ancestry I have 2 entries which slightly puzzle me. The names are followed by an alpha/numeric number. The 2 men are at the same address and have the same name and I'm pretty certain they are father & son. I've changed the names because one of them is probably still alive. They are: John Smith AZIE/96/1 John Smith AZA/4196785 (or4198785) The younger John Smith would have been old enough to have served in WW2 as he was born in 1919 but the older John Smith married in 1916 and so would have been pretty old to have served in that war. Has anyone got any ideas as to what these 'numbers' represent please?
