Still on the trail. Have been looking at marriage records for Joseph Notley's siblings in case a Johnson shows up as a witness

Have found a potential signature

I'm not brilliant with computers so am not sure how to post a copy of the signature I am interested in. If anyone could look up the following record and help me decipher the surname of the first witness I would be really grateful. First name is definitely William.
Record is Ada Notley m George Bunce 12/04/1903 Borough Wandsworth
Parish Battersea St George the Martyr.
Many thanks
