Hi Kiki
The surname is Butler and not Dutton.
About 5 years ago I got a copy of the marriage certificate and the surname looked very like Dutton. I subsequenty got a photo copy of the parish register from the church which is in a different hand and the name is William George Butler 23, bach., postman of 12 Rose Terrace, father Thomas Albert Butler. = Annie Jane Nowers 26, spinster, of 15 de Burgh Street, Dover, father Edward Wilson Nowers. Both signed. Witnesses:- Charles Frederick Sweet and Edith Nowers.This was on the 23rd of April 1898 at St. Mary. Edmonton. William's brother Robert Henry married in the same church the same day.
Tony Nowers.
