I think I have found him via the link from FamilySearch, the Morman site. It takes you to an image on FMP where the address is written as 4, Adams St, Aldelphi, Strand, WC ( i.e. London WC ) but the images either side are for Commercial St Newport and the transcript for the entry gives the address as 182 Commercial St Newport.
The image shows that Edward Forbes is a medical doctor, MB, aged 27 so born 1884 not 1894. his p.o.b looks like Dunmonway Co. Cork but is transcribed Dunnanway. He is a partner in a medical practice, the head of the household was originally written in as James H**ley aged 46, a medical doctor from Co. Cork but he is crossed out and Thomas O'Donell from Dublin a locum is given as the head of household. It is he who has signed the entry, I wonder whether he has just arrived as a locum and has put his London address in error?
The ref is RG14PN31972 RG78PN1840 RD587 SD2 ED13 SN509, Newport, RD 587, ED13 Pc 31972
I hope that helps
