Can I chuck what might be a spanner in the works,  and ask why you think Samuel from 2 Swan court is a brother of Emanuel?  and is this the only reason for thinking Emanuels father was Philip?   I have found records of various Phillips at various numbers Swan court and although they are probably related they are not all the same imeadiate family.
