I wonder if there is any connection between this woman and the marriage of Anne R. Ferbrache to Roy Filmer at Wandsworth in 1961?
I found the details on a website by Kevin Young. It lists the names of two children from that marriage. http://homepage.ntlworld.com/kevin.young7/f_99.html
Perhaps you should try contacting Mr Young if you think the above information is of relevance. Here is his e-mail address from the website but don't be surprised if it is defunct as the website looks like it hasn't been updated in ages:email@example.com
Maybe also try re-posting this appeal for information on the Guernsey board rather than on the Channel Islands one:http://boards.ancestry.com/localities.britisles.channelislan...
