Update
Received the birth cert for William Frederick Macey, in 1868 as suggested by Helina. Mother is Hannah Macey previously Arnold and father Frederick Macey. I am still a bit concerened about the age difference when William marries Florence he is said to be 28 but this birth would make him born about 1870 and not 1868. However I think it's possible that Florence was not yet 18 either and in fact amy only have been 16.
Anyway I am going to go with this one for now and hope it works out okay. Thanks for all your help
