Not sure where on the electoral roll you got your information. Was it via someone else's transcription?
From the online electoral roll, which shows actual page:
In 1935 John McLoughlin was on the electoral roll at 310 Pershore road
But John Augustine McLoughlin, Louisa Emily McCloughlan, John Morris McLoughlin, & Joan Emma McLoughlin were at 30 high St Kings Heath. this was not far from the Cross guns
