I,ve just checked on the 1901 census - there is a William G Ralphs, aged 26(!!), listed as son of George and Sarah Ralphs, living at 5 New Bridge Street.
My memory of Wolverhampton is also fading. Where is New Bridge Street?
The interesting thing though is that he is listed as being a pattern maker. Can there be more than one William G Ralphs whowasa pettern maker?
Hope this is helpful

P.S. If you come across anything about James Foley, born West Bromwich 1885, or his elder sister Josephine, born 1883 I'd be very grateful
