Does anyone know anything about a john cain 13 fredrick st 1919-1920? i found him on the electoral roll. Also seeking info on a ? walker 14 fredrick st., maybe the owner???

Now we come to the military. in ancestry they have my grand dad [ my mams father ] down as henry cain, 1894. he is robert henry cain, his father john henry cain. they also have grandad down as harry and harry is how we knew him.

There is more i want to ask but need to find a way to put it in writing so you will understand and i will not confuse anyone.
