There are many possible birth matches for Herbert on the Wirral, but none for Herbert V.  As most have second names, only one or two are possible matches (assuming he is from the Wirral), but are probably too old.

Death Indes gives us another Hervert V Lewis born in Wolverhampton which is a far more likely match.  Also, we know there are no Herbert Lweis's in 1911 in Birkenhead, so this also implies an outsider.
