To me, it looks like 'AGNESS' followed by a '9'.A quick search on RC brings up a number of threads involving the surname AGNESS in Essex and Suffolk. Does Edward have any links to that area?The '9' would probably relate to the registrar's note in the right-hand margin, indicating an alteration or addition to the register entry (hence the underlining?). Sadly I can't interpret that note.
To me it looks like Agness 9, maybe a miswritten address?
I agree with Carol - it appears to br Agness, underlined because it is an amendment.The amendment is numbered 9, which is cross referenced to the margin note “Nine OB” i.e. OB (denoting the registrar) has initialled amendment 9.
